That's what I would do before you get a full on cannibalism out break. A personal experience with the production reds.Those pinnless peepers look a bit crazy - never seen anything like that before. I think I'll just eat a couple of the hens for supper and hopefully that'll solve the problem. I'm not out in the coop enough to see what's going on. I water, and clean and collect eggs everyday - so I'm only out there with them maybe 5 mins a day max.
I have a 6 foot x 8 foot coop with 22 foot of roost space (1x4) about 6 foot off the coop floor and about 1200 square foot of fenced in chicken yard for these 18 chickens.
If I hear you guys right I got a "mean" chicken. I think I know which one it is she tries to peck me at times - maybe I'll have me some mean chicken soup then
The pecking ends when the mean bird dies. Next time you water the birds watch to see who drinks first. See who stands off to the side and waits. Are the ones that wait missing the most feathers? suspect #1 the prettiest one. Literally your birds are trying to eliminate competetion. In nature they would run off the other hen but confined hens have no where to run. It is a slow death so get rid of your bully/bullies and keep the sweeties.
The reds I had did this to my buffs and if i had known then what I know now I would have culled every red from my flock the day I saw the first buff bare back. Because two days later bare backs became bloody pecked to the bone backs.
