So I have my oldest rooster, Frank Feather Foot. He is about 4 months old and he has his group of 8 hens. Well, in a week the other chickens will be 8 weeks old and overnight we were gonna put them in the coop with Frank and his girls. (We read that overnight was the best time to bring in new chicks) So will Frank give the other 2 smaller roosters a hard time? My coop is about 6ft x 14ft and can 3 roos live in there happily or will it be a big fight???
