In the last couple of weeks, I noticed that one of our orpington roosters was becoming more aggressive. Last night while checking their food & water, he came after me. I booted him across the yard & figured that he had learned his lesson. This morning while riding her bicycle, my daughter was attacked. Thank god she wasn't injured. I CAN tell you for a fact that he has learned his lesson this time, compliments of a 22 caliber rifle. My daughter was more than happy to help pluck & clean him. Although I'm mew to the chicken thing, I never thought that the buff orpington would be an aggressive breed.
