I have 5 golden commet hens who are pecking eachother. It seems to have just started this winter. Everyday they are losing more feathers, two of the hens in particular, the other 3 are not too bad at all. I went to check on them today and the back of the neck of one of the hens was bleeding and feathers are completely gone. The other of the two has a bald patch on the side of her neck. I don't know what to do with them. Why are they pecking at eachother? Are they bored? I have a light on in the evening for a little while too.They don't get alot of free range time because of the snow. They do come out into their run during the day... most of the time. We had a really bad cold spell for a week or so, so they were in a lot. Should I seperate them and what should I put on the hens wound? Thanks!!
