Hello all, I have 19 chickens with 1 main head master roo who takes very good care of his girls, almost 1 year old. And 2 very sweet 5 month old little roosters, everyone gets along great as of now. My question is will I be able to keep them all as the younger ones mature? will they eventually start fighting each other? Are 16 hens not enough for all three of the guys to get along? Thanks so very much!
