compartments. The nests may be built in tiers and located on the walls at
either end of the house and on both sides of the center partition. If trapnests are to be used they should be located along the front of the house.
An egg carrier may then be constructed that will hang from a track similar
to the litter carrier.
O.S.C. 400-Hen Laying House
By
A. G. LUNN and W. J. GILMORE
of the hardest problems in successful poultry keeping is to mainONE
tain the vigor and health of the flock. Housing has particular bearing
on this problem. If the laying-house is poorly lighted, has insufficient
ventilation, or is overcrowded, the health
of the fowls will be affected. The purpose
of housing is to increase productiveness.
In order to accomplish this the fowls must
be comfortable.
So far as is now known there is no one
style of laying-house that will suit all conditions.
Ventilation. A ventilation shaft has been provided for each 100-hen
capacity. The shaft is 15i inches square when made of wood or 15i inches
in diameter when made in circular form of galvanized iron. The shafts
open at the ceiling with an air-outlet control slide provided as shown in the
plan. For winter use in Central and East-
ern Oregon the shafts should extend to
within eighteen inches or two feet from
the floor. On the front of the house the
air inlet is controlled by the cel-o-glass
frames, the frames being opened, partly
opened, or closed according to weather
There is ample evidence that
conditions.
fowls may be kept successfully in different kinds of houses.
Water fountain. The plan shows a
circular water fountain that has been used
successfully at the College and by poultrymen throughout the state. It is cheap
The 0. S. C. 400-hen laying house has
been in use at the College and by poultry
keepers throughout the state for a number of years. As improvements have been
found the plans have been altered accord-
in construction, easy to install, and requires but little labor to clean. It consists
of two parts: a water pan and a cone or
ingly.
funnel-like holder in which the pan rests.
To the funnel is soldered a piece of twoinch down spout which carries the overflow to the waste pipe. Your local tinsmith can make the fountains. For
winter use the rod type of electric water heater can be used by bending it
into circular form.
Egg room. A detailed plan of the egg
storage room is given in Extension Bulletin 445, How to Construct an Insulated Egg
Interior of 0. S. C. 400-Hen Lay ng-house.
Dimensions. The house is 20 feet deep
and 70 feet long. This includes a 10-foot
feed room in which an insulated egg storage room is provided. There are
1200 square feet of floor space provided which, on the basis of 400-hen
capacity, allows 3 square feet per hen. This has been found satisfactory for
a flock of this size. If it is desired to house more than 400 fowls the house
may be extended in length 13 feet for each additional 100 fowls.
Floor. From the standpoint of durability, sanitation, ease of cleaning,
etc., the concrete floor is recommended. It is important, however, that
coarse rock or gravel be laid under the concrete as a foundation in order
to protect the floor from dampness which otherwise would come up from
the ground. The plan shows the floor construction. It is also important
that the surface of a concree floor be troweled smooth. Otherwise diffi-
culty will be experienced when cleaning out the litter.
Under some conditions a board floor will be found best. A board floor
plan is shown in the drawing. It will be noted that a double floor is provided with an air space between. It has been demonstrated that such a
' floor is warmer and will cause less trouble from damp litter than a single
floor. Four-inch flooring is specified as wider material will buckle and
cause trouble when cleaning.
Nests. The plan shows the construction details of an open type of
nest. Allowing one nest for each four hens would require 100 nests or

Blue-print. For those desiring a larger working plan, an enlargement in blueprint form 24 x 35 inches in size of the
drawing shown in this circular may be
obtained for $1.00.
A detailed blue-print of the ventilator
cap may also be had for 250.
Orders for blue-prints should be sent
to Department of Poultry Husbandry,
