clean. If it is a lamp brooder, the lamp 
should be lit up and kept burning at least 
twelve hours before chicks are put into 
it; the lamp should be cleaned and filled 
at least once~ every day; the regulator 
should hold the temperature up to 95° F. 
before the chickens are put in. After the 
chickens are put in, the heat from their 
bodies will raise the temperature in the 
brooder to 98° F., or perhaps more, and 
you may find it necessary to lower the 
lamp a little in order to keep the tempera- 
ture from rising too high in spite of the 
regulator. The temperature .of the 
brooder should be watched very closely 
for awhile, until you are sure it is going 
to remain about right. The chicks should 
be allowed but little room outside the 
brooder for at least a week; by that time 
they will have learned how to use it and 
they may be allowed more room. 
Don’t crowd your chicks. As with the 
breeding stock, crowding is fatal to suc- 
cess; there should be five hundred square 
inches of space under a brooder for each 
fifty chicks; ten square inches to the chick 
is about right for the first two weeks, 
after which the space should be doubled.
