We're going to be buying some straight run bantams (silkies, I think) and I was wondering how many we should buy. I assume the odds are supposed to be 50/50 for girls. We have a 6x5 coop with two levels. How many banties can realistically fit in that space (they will be allowed to range for a while almost every day). How many banties are good for that space, and how many straight run chicks should we buy to get about that many? We do have a place for the males already lined up since we can't keep them here in suburbia. Thanks in advance for your wisdom. My husband and I are having a hard time deciding on a number.
