I have 7 bantam pullets (at least I think they are all pullets). I'm new to chickens and I've been reading lots of info here at BYC. It seems that roosters do a lot to protect their flock of hens....do I need one? I will be keeping the hens at our ranchette, which is approximately 1 acre in size, with 6' block walls around the whole area. My two horses will also be there, but not sure if they will be of any protection to chickens? I am aware that there are racoons in the vicinity, probably hawks and owls too. We're setting up the extremely secure coop with auto door closer/opener for them so they will be safe at night. But do I need to worry about them during the day? Would a rooster really make much difference?
