    Read an article that claims the roos tend to not develop with cooler storage temps.
    Wondering if any one noticed that?
    There was no difference in sex ratio between chickens hatched from eggs stored at 60 and 80°F, neither departing significantly from 50 per cent. pullets. However, storage at 40°F produced significantly more pullets than cockerels, 54.6 per cent. of the chickens being pullets. Storage temperature and age of egg did not affect the hatching weight of the chickens, but when 14 days old, pullets from the eggs stored at 80°F were significantly heavier than pullets from the other groups."
