Those of you who breed chickens... Do you run your hens together with all the roos when you aren't setting/saving eggs? I have some really nice BRs I'd like to keep eggs from. Also have several sexlink and RIRs that I don't care to breed. Do you keep your breeds separate all the time or just when saving eggs? If together and the birds are of similar size, do you put all the roos in with them or keep the roos in a separate pen altogether? Thanks for the info.
