Hi folks, I need some help figuring out what is going on and what to do about it. Sorry in advance for the length, but I have to give some background first: We started with 2 hens who got along well, Molly the boss hen/best layer and Lucy the little hen, also a good layer. They lived in peace and harmony, and layed lots of eggs. In early Spring, we got 3 chicks, and when they were 2 months old we got a rooster who was the same age. We put the 3 pullets and baby rooster together (after proper quarantine) with a divider in the run so the 4 youngsters could get acquainted with the 2 adults, but eat and roost separately. The 3 pullets and baby rooster got along great, Molly the boss hen was not a big fan of the rooster but she tolerated him as long as he let her be boss, and Lucy the little hen was unconcerned. After 2 weeks we took out the divider, but left the little coop in the run so the youngsters could hide there if needed. We let them out to free range on weekends. Everybody still got along fine, occasionally Molly would chase at rooster, but never peck or really attack. Soon they were all roosting together in the big coop, the 3 pullets started laying eggs and became hens, and baby rooster grew tail feathers, started crowing and mating the hens, and became Ragnar Lothbroek (extra cookies if you watch Vikings) Ragnar was never very aggressive with the hens - he jumps on them to mate, but never grabs or pecks. He always defers to the hens when there are extra treats, he even sits on the eggs occasionally. A week ago, Molly the boss hen/best layer, had a horrible wound on the back of her neck. She's currently hospitalized in the chick house in our laundry room, and recovering very well, thanks to all the wonderful information on wound treatment I learned here! We never saw what happened, and at first we were guessing - maybe Ragnar did it. Did he finally decide to fight her for the right to be boss? Did she refuse to mate with him, so he grabbed her by the neck? He has never shown any aggression towards the hens or us, but maybe he needed to assert his new roosterness? But now, after observing the flock for a week without Molly there, we're thinking we might have judged Ragnar unfairly, and the culprit might be Natalie, the young barred-rock hen who just started laying. She follows Ragnar around constantly, and pulls feathers out of his neck. She never shows aggression when she does this, just stares at his neck for a second, then grabs a feather. Then does it again. And again. She never stops, she is relentless! Poor Ragnar never retaliates, he tries to do his duty to mate all the hens and protect them while free-ranging, but we can tell he's really bugged by her. His poor neck is so plucked, he is starting to look like a turkey. And the other hens are tired of having no peace, they are constantly getting out of the way and hiding, while Natalie chases Ragnar around the coop to pluck his feathers. Natalie never picks on any of the other hens. We're still not sure if she is the one who pecked Molly's neck to a bloody pulp, but the other hens would never do that and Ragnar comes across as a good citizen of the flock. All of you more experienced flock-meisters, can you tell me if I'm wrong? If not, why Natalie is doing this? Maybe she wants to be flock-boss, and she's trying to take down her superiors, one-by-one. Maybe she's lacking something in her nutrition that makes her attracted to feathers (except she doesn't eat them, they're scattered all over the run.) Maybe she is a sociopathic hen who is mentally disturbed?! Natalie's a beautiful hen who's turning out to be a good layer, and I'd prefer to keep her, but the eggs she lays are not worth the discord in my coop. I'll cull her if that's what it takes to keep peace in my flock. Please tell me about all your experiences with your pecky hens, and what you think I should do.
