VARIABILITY IN EGG PRODUCTION 



11 



unfavorably on egg production. Production responses to temperature changes 

 seem to follow soon after the temperature changes. On the whole, the effects of 

 variation in house temperature on variation in egg production are not very sig- 

 nificant for the birds studied, and house temperature may be placed among the 

 minor causes of variabihty in production.
