About a week ago I went and got two peahens from a lady my moms knows. She said they're both about 10 months old, so they're not adults yet. Well when we got home with them my brother accidentally let one, we call her Betty, go and she took off for the woods where we thought she'd never be see again. Just last night I went and picked up two peacocks and another peahen to replace Betty. When I got home, around midnight, I went to check in my coop to make sure all my baby chicks were safe inside and low and behold, Betty was there. Needless to say I was really surprised. I quickly threw her and Rose, the other peahen I got with her a week ago, out into their enclosued yard because I noticed she had gotten in through a weak part of the roof and I didn't want them getting back out. Well today I went back out to fix the roof and I've noticed Betty is just being a real butt. Anytime any of the others walk past her or look at her funny she goes after them. She's picking out feathers and making them screech. They're all around the same age, 9-10 months old. She's especially mean to my white peacock, can't stand to look at him. She's been doing it all day.
My question is, finally, is this normal behavior for a peahen? Is she just trying to show she's the dominate hen? None of the others seem to mind eachother. If it continues I'll have to get rid of Betty, which I really don't want to but she's just being a terror. I'm afraid everyone is going to go bald if I leave her in with them.
