Hi there, I'm hoping someone can give me an idea of what this hen has. She is old and I would like to give her a chance to walk again properly if I can. She was given to my elderly parents a few years back and often went off into the forest. She was very hard to catch and the only time we could catch her was when her nails got too long. At that time, I think she would have had scaly leg mites. When all the other hens would come up to the house to get food she wouldn't so I suspect she has always had some sort of foot problem from when she was given to them. But she always managed to join them in the hen house for the night. I now have her at my house, in a cage inside the house lined with newspaper. I brought her home to give her some more intensive treatment as I noticed she is unable to perch now. I have had her for 2 weeks now, smeared vaseline daily (sometimes twice daily), given her a weekly bath in epsom salts. I managed to get a huge hard black lump off her lame foot after over 30 mins of soaking it. It was yellow inside. I bandaged the wound and changed the dressing every day for 3 days then let the air dry it out. She was able to put pressure on it and got to the point where she could stand on it for a short time but today it has gotten worse I suspect as the yellow stuff grown over where the wound was has gotten bigger. She doesn't want to put any pressure on it. Today I gave her another bath with epsom salts and a drop of Tea tree oil and Oregano. And now I am trialing coconut oil instead of vaseline because it has antibacterial and anti fungal properties. I guess I really want to know what the yellow stuff is and how to stop it growing back. I'm pretty sure after some time it turns black and hard. Sorry for the gross photos, I took the one of her leg after I put coconut oil on it. I haven't been able to take a photo of her worst foot as she keeps it tucked away but her better foot also has the yellow scabs and black stuff as seen in photo.
