My question kinda got burried. I'll reask it and see if anyone has any ideas? I bought that mille fleur breeding pr on the 24th, they were free ranging with brahmas and "generic" red chickens about the size of RIR's. She said they pretty much stuck together all the time and says that the eggs will most likely be purebred, but I just don't feel comfortable selling the eggs to people and then they end up getting mixed breeds. Know what I mean? How long do I need to wait to be sure they're purebred? For example, human sperm can live for 4-5 days, is it the same for chickens? In the future, if I were to breed 2 chickens 1 time and I were to separate them, how long would I get fertile eggs for?
