I had a week old adoptee that pecked everyones eyes, and actually pinned down a chick and pecked her eye till it bled. I did not want that kind of agression in my flock! After he left, everyone is happy and getting along. I didn't like getting rid of it, it was horribly hard, and I hope hope hope I never have to do it again, but am satisfied that I did it. We tried to seperate, put, a bigger chick with him/her, distract with something else to peck on, but to no avail. He/she was like one of the bird dinosaurs from Jerassic Park. I sure wouldnt want to see what it was like as an adult!
