My rooster (22 week old BJG) decided to chase attack my husband a few weeks ago, and DH was steaming mad ready to have chicken dinner. I convinced him that is was teenage rooster hormones (I made that up, lol). I thought that he deserved another chance. He kept attacking/ flogging anyone who went into the pen to open the pop door. I decided to use the bad rooster rehabilitation advice I read here on BYC and went with my muck boots and jeans and some bread for a treat. As soon as I entered the pen he flogged and pecked me, so I knocked him off with a little kick from my boots and he came back at me. This repeated several times, but eventually he gave up and I offered him the bread. When he went to take it I snatched his rooster butt up and tucked him under my arm and carried him all around the pen, while I talked to the girls and gave them treats. I pet his head and rubbed his wattles, which he hated but he didn't peck at me. After about 10 minutes I put him down expecting him to attack me again, but he didn't, he just turned and went into the coop to pout. This was on Monday and he has not even raised hackles at me since. I'm going to give him a few more weeks before I send anyone else into the pen with him, but I think his attitude has really changed.
I don't know if this would be worth trying to you since you have two other roosters, but I only have the one that is the same age as my girls and another orphan rooster that lives in the barn with my turkeys.
