I'm down to 25 laying hens and I have 3 roosters, all Buffs, all less than a year old. My smaller rooster is 8 weeks older than the other two. I'm having a problem with the two younger ones (about 9 1/2 months old) one of them was a late bloomer, and with two taking care of the girls, everything was fine. When the bloomer started tending to the girls, he would run them crazy, hurt them, stand on their back after he finished, etc. When he started, the other young one (which originally was a good rooster) now acts exactly the same. I have isolated the young one, trying one at a time with the older rooster, but the behavior continues, so they are being culled. My question is, will one rooster be enough for 25 hens?
