We have 8 older hens (4+ years old). They were never with a rooster before. We got 24 chicks in mid-April; four NH Reds, four Barred Rocks, the rest Easter Eggers. We bought them at a local grain/pet store. We were told they were all pullets--no guarantees, of course. It didn't take long to discover we actually have FOUR roosters; one NH Red, the other three EE's. So they're about 5 1/2 months old. We don't see any fighting (yet?) among the roosters...but they've been furiously mating with all of our hens--including the older gals. The older gals are starting to seem quite stressed and getting more exhausted. Should we put the matrons in their own box stall? Is it possible for the roosters to wear them down too much causing them to ultimately die? Would help/hinder the situation if we remove one/some of the roosters? Any tips, suggestions, advice are gratefully appreciated.
