I need some help finding a solution to a problem that has started among my chickens. I have 4 hens and 3 of them have singled out 1 to be the lowest on the pecking order. She gets chased from the food until the others have eaten, etc. I know this is normal. I came out to let them out one morning and I noticed that this particular hen was missing most of the feathers on the top of her head. I read that this can happen, and began watching them throughout the day. The 3 other chickens did not act aggressively toward her at all all day. They treat her normally and don't do anything to hurt her. This went on for a few days, until one night when I went to lock up the coop, I noticed that one of the hens, the alpha, who has always been skittish, got nervous that I lifted the lid to the coop to straighten things up and began pecking the heck out of the poor girls head. I immediately pushed her away and thought she must be the culprit who's doing ripping out the weaker ones feathers while in the coop. A couple of days later, I wasn't able to let the hens out at the normal time. I was about an hour late. I normally let them out to feed about 7:15-7:30am. When I opened the coop the bullied hen had her comb bloodied and the back of her head was a bloody mess. It had never been that bad before. I cleaned up the injured hen, and at night seperated her until she healed. She's fine now,, but still low hen on the totem pole. This morning I got out to the coop about 30 minutes "late" and lo and behold, her feathers are all ripped up again. I've noticed when I get out there in the morning that one of the chickens especially, is going nut, frantically pacing back and forth trying to get out. I've provided plenty of room in the coop. Im starting to wonder if it's this hen, and not the alpha that is just ancy and takes it out on the one hen if she's not let out on time. This hen has begun even pecking the alpha if she gets too close to her at night in the coop. The only two times this has happened is when I've been late. Any ideas beside the obvious, "don't be late" regarding what I should do? They eat well, have plenty of space, free range. It's only in the morning if I don't let them out "on time". I also noticed that the 3 hens did not do this to one another when the injured one was seperated from them in the mornings.
