Hello all-- This is my first time posting here...I have five hens that free range during the day and go into the coop at night. They are about 6 months old and have been laying for about one month. These are the first chickens I've ever had, so I'm new to all this!! This morning, one of the hens has a quarter sized wound in the middle of her lower back. All the feathers are gone from this area and it is bleeding a little bit. Not sure how the wound started, but I'm assuming the other hens pecked at her last night...During the day, when the girls are out where I can see them, they all seem to get along, I have not seen any fighting. She is separated from the others for now, but I have a few questions as to what to do now... 1- How should I clean/treat the wound? 2- When can I put her back with the others? When the wound is totally healed? When all the feathers have grown back? 3- How long will it take for all the feathers to grow back? 4- Any suggestions for preventing this in the future? Any advice is welcome!! Thanks so much!
