I have 24 chickens 2 are rooster that i know of this far. They are 12 weeks old. One of our roosters "Randy" will go around and peck all of the others tail feathers, they will squawk and at first we thought it was kind of funny, no big deal, but he just seems to be getting worse we noticed yesterday one of our hens had a huge wound where he has pecked her so badly, we immediately put her in a dog kennel so he couldnt get to her and got some spray to spray on the wound. Any ideas what i can do to get our rooster to stop this? Is this normal? I really have grown attached to my chickens over the paat 12 weeks and would like to keep our rooster around if possible.
