I could really use some help here. I have 4 White Sultan hens. 3 of the 4 have this growth on them. I started using Neosporin on one bird the last couple of days (without pain relievers) and it started to improve. The first pick is of that bird. I put her inside, since it was so cold outside and put another WS who was bloody from being picked on so they could get a chance to recuperate. I put them back outside today, since it is warming up and noticed two others have the same growth. What is it and am I on the right path? Suggestions? BTW, I checked all the rest of my flock and no one else has this.
