I noticed something was wrong with my Partridge Rock pullet's neck about a month ago. Her feathers were all puffed up on her neck and she seemed to have an odd sort of injury, a big, thick scab. Here's some pictures. I cleaned it off and pulled out any bloody, dry feathers. I looked at it again, and it looks much better.The scab is nearly gone and all the feathers are coming back, but there seems to be a really large lump or growth of some sort on her neck. I'm thinking about having it checked out by a poultry vet. Here's a picture: Any thoughts? Thanks in advance.
