I have 5 chickens all about 5 months old. Three are one week younger than two. I noticed yesterday that one of them has a bald spot by her vent and a sore. Later in the evening I discovered that another one had a sore. I had already separated the one. I know one of them that has been pecking those two. Today, I checked the first one and saw that her sore looks a little bigger and yellow but like a scab and nothing seeping and more balding. I have been doing things in their coop for the last couple of hours in order to separate the two wounded ones from the rest. The second one I discovered has a couple sores.I put hydrogen peroxide on them both but no fizzing occurred. I also put triple antibiotic ointment on them both. I noticed hen #1 that has the more bare spots was either trying to get the medicine off her feathers or trying to pluck her own feathers. I also read that putting vicks on all of them would discourage the pecking. I bought what is literally called a pecker breaker (hanging treat for them to peck at). During the time I was with them after applying the vicks they seem to be leaving each other alone. Does anyone have any suggestions or comments that may be helpful. I am concerned about the wounds getting infected if the one isn't already.
