Floor Growing Recommendations—Alternative Systems
It is essential to grow the birds on the floor when they will be
housed in floor systems for the laying period. Ensure that the
feed and water systems in the growing and laying facilities are
compatible. Ideally, the growing house should have elevated
bird walkways with feed and water stations. Flocks housed in
all-slat houses during lay should also be grown on slat or wire
floors.
Chicks started on the floor should be transferred from the
transport boxes to the litter under the water lines or near
drinkers to encourage drinking. To make it easier for the chicks
to drink, use supplemental drinkers in addition to the automatic
drinkers. The supplemental drinkers should be used for the fi rst
10 to 14 days and can also be used for administering the fi rst
vaccination if given in the water. When used, gradually move
supplemental feeders and drinkers towards the permanent
feeders and drinkers in the room to train the chicks to find the
permanent feeders and waterers.
Birds should be grown in housing that allows adjustment to
the lighting program and the light intensity. It is important to
provide floor-grown birds with enough light intensity to allow
them to navigate their environment. A light intensity of 20 to 30
lux (2 to 3 foot-candles) should be used during the first week of
age, dropping down to 15 lux (1.5 foot-candles) by week 4 and
remaining at the level until week 15 of age. At week 15 of age,
gradually increase the light intensity, reaching 20 to 30 lux (2
to 3 foot-candles) by the time the pullets are transferred to the
layer house. Birds moving into open-sided housing should have
higher light intensities of 30 to 40 lux (3 to 4 foot-candles) at the
time of housing.
Birds are very sensitive to extremes of relative humidity. A
relative humidity below 30% will cause increased agitation of
the chicks and may cause aggressive behavior. Conversely,
excessive moisture may cause wet litter conditions, associated
with high ammonia concentrations, poor air quality, enteric
diseases, and respiratory problems. Ideally, the relative
humidity should be between 40 and 60%. Humidity control
becomes increasingly important when warm-room brooding in
cold climates. To increase the relative humidity, water can be
sprayed on the walk ways or fl oors. Humidity will normally be
lowered to 30 to 40% by the end of the growing period.

Ambient Temperature and Relative Humidity
Observing the chicks will tell you whether or not the
temperature is correct. If they are too cool, they will huddle (or
crowd) near the heat source. If they are too warm, they will
spread out away from the heat source. If there are drafts, they
will huddle in groups to get away from the spot where the cool
air enters the heated area. Comfortable chicks will spread out
uniformly, without huddling, throughout the brooding area. Look
for signs of overheating (panting and drowsiness) or chilling
(huddling and loud chirping) and make appropriate adjustments.
Water Consumption for Pullets and
Layers
Drinking Water
Water is the most important nutrient and good-quality water
must be available to the birds at all times. Only in special cases
(e.g., prior to vaccine delivery through the drinking water),
should drinking water be restricted, and then only for a short
time and under careful monitoring.
Monitoring Drinking Water Intake
Water and feed consumption are directly related—when birds
drink less water, they consume less feed, and production
quickly declines accordingly. As a general rule, healthy adult
birds will consume twice as much water as feed, although the
ratio increases during periods of warm weather. Installation and
use of water meters in each house or barn are recommended
to monitor the fl ock’s water intake on a daily basis. Such daily
water-intake records can be used as an early warning of
problems in the fl ock.

* Chart shows an expected range of water consumption at normal
environmental temperatures for bird comfort (21–27°C). At higher
temperatures (32–38°C) water consumption may increase up to double
the amounts shown.
Nest Training
Confine the pullets to the slats (where the water and feeder
lines are) at housing and allow the pullets access to the nests
at housing. Walk the birds several times daily, particularly in
the morning, to ensure the birds are finding feed and water. To
reduce stress and ensure a trouble-free transfer, water-soluble
vitamins, probiotics, and vitamin C (ascorbic acid) can be
added to the drinking water 3 days before and 3 days after the
transfer.
Open a few of the nest box curtains to encourage nest
exploration in young laying flocks. Nest lights can be used
to train birds to explore the nests and should be turned on
for 2 hours per day, starting 1 hour before the house lights
are turned on and remain on for 1 hour after the house lights
have been turned on. This will help prevent overcrowding and
smothering inside the nests. False walls that are 1–2 m in
length every 12 m along the line of and perpendicular to the
nest boxes will reduce nest overcrowding.
Train the pullets to use the nests by frequent walks through
the house in the mornings for the first 8 weeks after the birds
are placed in the laying house. Use of electric deterrent wires
on the slats around the house perimeter will help discourage
egg laying in corners or near the walls. Electric deterrent wires
must be turned on as soon as the birds are housed. Place
the electric deterrent wires 5 cm away from the wall or the
house and about 10 cm above the fl oor. Avoid using an electric
wire over water and feed lines as this practice increases
nervousness among the birds. Instead, the use of solid perches
above water and feed lines is preferred.
Floor Systems Management
The Hy-Line Brown can be used successfully in floor systems
due to their good livability and nest behavior when the birds
have been appropriately socialized. It is important to provide
the birds with the best possible floor environment to achieve
the performance potential of the Hy-Line Brown. It is essential
to grow the birds on the floor when they will be housed in fl oor
systems for the laying period.
Check the lighting program and intensity and synchronize with
the growing house. The Hy-Line Brown will need bright light
and it is important not to have any shadows in the house. Dark
areas outside the nests will encourage floor eggs.
The litter area in layer houses should not be more than 60 cm
(24 in) below the slat area. Position lights to eliminate shadows
on the litter below the slat area. Position lights to provide the
brightest light intensity over the litter or resting areas and the
lowest light intensity at the front of the nest boxes. Flocks
housed in all-slat houses should also be grown on slat or wire
floors.
Socialization of Birds
It is important to socialize the birds raised on the floor to
humans by walking through the house daily. It is recommended
that the birds be walked 4 times per day with a 2-hour interval
between walkings. This would give the birds time to relax and
settle between walkings. Brighten the house and walk briskly
through the house to improve the process of socialization.

Lighting Programs
Egg production is very closely related to the changes in day
length. Body weight gain in the growing period, egg numbers,
egg size, livability, and total profitability can be favorably
influenced by a proper lighting program.
When open-type houses which allow natural daylight to affect
the flock are used, the lighting program must be planned in
conjunction with changes in the natural day length. Because
no two places have the same sunrise-sunset times yearround,
custom lighting programs for any location worldwide are
available.
The customizable lighting program is available in multiple
languages and will create a downloadable spreadsheet with
sunrise and sunset times for any location in the world and the
lighting program for your flock. Visit www.hyline.com to access
the customizable lighting program.
Controlling Egg Weight
It is recommended to closely monitor feed intake, body
condition (through body weight and/or body scoring/fatpad
development), and egg weight of each flock and make
nutritional changes as needed to ensure optimal production
rate and egg weight. If smaller eggs are desired, the egg weight
should be controlled even more aggressively at an early age.
Egg-weight control is achieved through a combination of
limiting amino acid consumption and ensuring that the feed
intake is not too high (achieved through control of the ambient
temperature). To avoid excessively large eggs later in lay, use
the peaking and second layer feeding phase diets for less time
than shown in the Performance Standards Manual. This will
provide a reduced level of added fat or oil, as well as amino
acid contents, to control egg weight.
Control of ambient house temperature
At housing, an ambient temperature of 21 to 23˚C is desired.
Increase the house temperature about 1˚C every 2 weeks until
reaching a house temperature of 26 to 27˚C assuming the
ventilation systems are able to maintain adequate air quality at
these temperatures). Lower (colder) house temperatures will
lead to greater feed intakes and may be counterproductive to
egg-weight control, as well as optimal feed efficiency and adult
hen body weights.
Perches
Perches provide a signifi cant improvement to the growing
and laying house environment. In grow, they allow birds to
fully develop their leg and flight muscles to develop jumping
behavior. This will be important to develop good nesting
behavior and if the laying hens are later housed in aviaries. In
addition, perches reduce the social stress by providing safe
resting sites. In part because of the improvement in social
pressure, perches can improve feed and water consumption,
with resulting effects on body weight gain, body weight
uniformity, and egg production. Perches also increase the
effective space in the house, and reduce piling which is a
common problem in fl ocks without access to perches. Perches
also help improve the social environment as mentioned above
and signifi cantly reduce occurences of eggs laid outside the
nests (i.e., “floor eggs”).
The dimensions for A-frame perches are shown in the drawing
to the right. If individual perches are placed too close to the
fl oor, birds cannot escape from social-stress situations. Perches
above the feed or water lines, perches extending from the wall
(i.e., half an A-frame), or other perch designs can also be used.
The perch length depends on bird density (see table). If space
allows, place perches on slats to maintain good litter conditions.
40 cm
The width (or diameter) of each perch should be 2.5 cm or wider to allow
for a comfortable grip. The length of all perches in the house depends in
part on bird density.

*Typical feed consumption for the age based on available data.
1
Consumption of amino acids, fat, linoleic acid, and/or energy may be changed to optimize egg size.
2
The recommended energy range is based on the energy values shown in the Hy-Line Red Book, an Online Management Guide. Differences in the metabolizable
energy value assigned to feed ingredients of the same name can differ substantially; in some cases, the recommended dietary energy content may have to be adjusted
accordingly (see the Hy-Line Red Book, an Online Management Guide for additional information).
3
Total amino acids are only appropriate with a corn and soybean meal diet; please formulate the diet on digestible amino acid basis if a substantial amount of other
protein-supplying ingredients are used.
4
Approximately 65% of the added calcium carbonate (limestone) should be in particle sizes of 2–4 mm.
5
This Peaking Diet should immediately follow the Pre-Lay Diet.
6
Change to Post-peak Diet when egg production has decreased 2% from peak egg production.
