HI! I have a Golden Laced Wyandotte rooster about 8 months old. He has been with my flock (4 hens) for a couple months, and up until about a week ago he was very nonaggressive. Now he is attacking me and my 3 children and our dog daily! I do love him and want to keep him. Why the sudden change, and is there any way to get him to mellow out?
