cement floor. Novelty siding is nailed on the outside of 

 the studs. There is no double boarding on the inside. This 

 building cost about $1050 and has given good satisfaction. 

 Note that the only hover we have is a burlap screen. 

 This is laid over about one-half of the space between par- 

 titions, therefore it is about 2j4 feet square. After the 

 ffrst few days it is removed. We also have a board about 

 12 inches high to keep the chicks within about two feet of 

 the pipes for the first 24 to 48 hours. It is then moved 

 back to about the middle of the run for another day or 

 two, and finally removed, giving the chicks the use of the 

 entire run. 



The pit is 4 l / 2 feet deep. If possible, it would be- well 

 to have a drain in this pit. In cold weather the water 

 could be run off easily without carrying it out. Further- 

 more, in cleaning a brooder house the work should be done 

 thoroughly, and by the use of a hose the floor could be 

 flooded and the water carried away by this drain. Of 

 course, it may not be convenient to do this, but in case it 

 is it will be well to provide for it. 



There are eight lJ4-inch pipes 5J4 inches from the 



FIG. 143 PIPE HEATED BROODER HOUSE AT MASS. AGRI. COLLEGE 



rear and four inches apart on centers. The pipes are seven 

 inches from the floor, but it would be just as well to drop 

 them one inch, making the distance from the pipes to the 

 floor six inches instead of seven inches. 



Each hover will take care of 100 chicks, although we 

 believe better results follow when the .number is reduced 

 to 50 or 75.

PIPE HEATED BROODER HOUSE WITH UNDER- 

 NEATH HEATING SYSTEM 



Practical House for Cold Weather Brooding. Pipes 



Under Brooder Floor. Hover Warm-ed By Gentle 



Current of Hot Air. 



Pipe-heated brooding systems with enclosed pipes 

 have been in use for many years and have given varying 

 degrees of satisfaction. A serious objection to this method 

 of brooding is that, as such heating systems usually are 

 installed, there is not a sufficient ventilation under the 

 hovers. In order to provide the better air circulation 

 needed, the pipes may be placed below the hover floor 

 and enclosed in a chamber or long narrow box where air 

 can be heated, after which it is discharged under the 

 hover, thus maintaining a constant air circulation which 

 automatically ventilates the hover space. Plans for a 

 house heated in this manner are illustrated in Fig. 144. 

 The house here shown is 140 feet long and 13 feet wide, 

 and is separated into two parts, 36 feet and 104 feet, re- 

 spectively. The short end has 12 pens of 3 feet each in 

 width and 10 feet in length, includ- 

 ing the hover, and the longer end 

 has 24 pens 4 by 10 feet in size. 

 The furnace pit and a narrow walk 

 separate the two lots of pens, and 

 an aisle 3 feet in width extends the 

 entire length of the- house back of 

 the hovers. 



The system of heating pipes is 

 installed under the hover floor in 

 a concreted trench. The shorter 

 end has a 2-inch flow and return 

 pipe. The long end has two flow 

 and two return 1^-inch pipes, and 

 both sides are controlled by valves 

 near the heat whereby all or a part 

 of the flow may be shut off from 

 the pipes. The trench is made by 

 excavating to a depth of 6 inches 

 and 36 inches wide. The sides and 



bottom are cemented and the top is boarded with a 

 course of rough 1-inch boards, covered with a layer of 

 matched %-inch spruce flooring (K). This double board- 

 ing prevents any danger of too much bottom heat. The 

 boarding comes flush with the edges of the trench sides, 

 and the frame work of the hovers is of Ix3-inch posts 

 which are only as high as the hover divisions (C), which 

 in the small pens are 10 inches and in the large pens 12 

 inches. 



This gives a house entirely free from inside posts and 

 makes possible a view of the whole interior from any 

 part. The hover floor is 3 feet wide (the width of the 

 trench) and in the 3-foot pens the hover top slides on 

 cleat (F) 6 inches from the floor. The top or cover is 

 only 24 inches wide, which leaves 12 inches of the slightly 

 warm floor in front of the hover curtain, making a splen- 

 did resting place for the little chicks or ducklings, which 

 they evidently enjoy. When first they are put in the 

 hover, they are penned back nearly to this floor and the 

 gentle warmth helps them and keeps the floor free from 

 dampness. The cover being in two parts (A and B) and 

 sliding freely on cleats (F), may readily be adjusted so 

 as to give ventilation at the back, front or center of the 

 hover, or all three, and the surplus heat may escape in 

 the same way. 



The hover floor is kept littered with chaff or shavings 

 and when the pen is to be cleaned, the hover top is re- 

 moved, the back boaid, which sets between cleats, is
