PROPAGATION 
Large flocks of chicks are more diffi- 
cult to succeed with than small ones, there- 
fore I would advise the beginner to start 
with a small flock and give them plenty 
of room. 
The bulb of the thermometer used in 
the brooder should be about one and five- 
eighths inches above the floor of the 
brooder for chickens, and for ducks a little 
higher, say about one and three-fourths 
inches. This is very important, for if your 
thermometer is too high or too low, you 
will be deceived, by its reading, into believ- 
ing that the temperature is right when it is 
not. If the bulb of your thermometer is on 
the floor of the brooder and reads 95° F. 
to 100° F., the temperature is much too 
high for the chicks, and if the bulb of the 
thermometer is much over the height that 
I have given, then if it reads 95° F. to 
100° F. the temperature of the brooder 
would be too low. 
The cause for this difference of tem- 
perature at different heights in the brood- 
er is the same as that which brings about 
the same results in the incubator. I 
explained this when I was writing about 
the incubator.
