INCUBATION AND BROODING 



day or two we do not like to fall below ninety degrees, and we 

 do not like at any time to exceed ninety five degrees. On the 

 seventh day the chicks are passed on to the pipe system, the first 

 pen of which is three feet six inches wide. Day by day they are 

 passed forward, each pen increasing one inch in width, giviAg 



the six-weeks chicks a space of six feet six inches — more than 

 double the space they started with. Six days after the first 

 hatch another hatch will be ready and the newly hatched chicks 

 will be put into the lamp brooders, and so the house is kept 

 running just as long as required.

HAMMONTON HOT-WATER PIPE 

 SYSTEM BROODING HOUSE _ 



The accompanying brooder house plans (Figs. 1 and 2), 

 show the style of house in use at Hammonton, N. J., and else- 

 where. In this style of house the hot- water piping system is 

 used, and instead of decreasing the number of chickens in each 

 pen as they increase in size, the size of the pen is increased. 



1! The brooder, as may be seen in Fig. 2, consists of boards 



•nailed together with cleats, which rest on four hot-water pipes. 



In the brooder house at Hammonton strips of carpet aresus- 



The pipes should be three inches from the floor for the 



pended from each side of the "brooder," and also between the 

 pipes, nailed to the vmder side, with the fringed edges of cai-pet 

 (double or single), just high enough so the chick can feel it on 

 its bapk, and here is where they Uke to hover. 

 ^ ■ s ■ It will be observed that the pens grow larger towards the 

 .end away from the heater. The first young chicks are placed 

 in pens A to G, to be followed by the next new hatch, and these 

 earlier chicks are removed to larger pens. This shifting from 

 pen to pen goes on until the house is fuU. The chicks that have 

 progressed by successive stages to pens K, L and M are fit for 

 broilers, and are marketed as fast as they are ready. The chicks 

 have grown and need the largerjpens to accommodate them. 



smallest chicks, and from five to seven inches from the floor for 

 the largest, having a uniformly upward slant from pen A to pen 

 M. The brooder tops are twenty inches wide, and should be 

 fined with paper on the under side. They are movable, each 

 brooder top extending the width of the pens only. It is custo-

brooder house, where the incubators are kept. The chicks can 

 thus be transferred to the brooder without inconvenience. 



These pipes are fed with hot water from a stove or furnace 

 located in an excavation at the A end of Fig. 1. The hot water 

 circulates to and fro through a coil of pipes. The brick foun- 

 dations are a protection against rats, mink, etc.
