I have 15 hens (3 of them 6 months old and the rest 12 months old) and 1 rooster (also 6 months old). He started mating with all of the hens about 3 weeks ago. Unfortunately he is getting very rough with the girls. He is pecking and pulling off their feathers, and has just started pecking my leghorn’s comb to the point it is bleeding at times. Now I’m wondering what to do? Should I separate the leghorn? And is there anything I can do to calm down the rooster? When I pick up the hen to inspect her he gets very concerned, and goes after her when I put her down. He is nothing like his father, our first rooster who was unfortunately killed by a neighbor’s dog. I just put some dried lavender in the coop thinking that might mellow him a bit. Any suggestions?
