I have one out of nine chickens that has started laying....inconsistent, but laying. They are all 19 weeks old. Black Australorps, RIR's, and a lone Buff O. My question is, once the Oklahoma heat subsides, (114° for wednesday) and we start the downward side of the heat, and they stop panting so much, should I be expecting a regular pattern of egg production since they will all be in the range of maturity? This being if I have nine NORMAL hens? Thanks for the responses in advance.
