Weird lump on chickens foot?

[Remiel]

I first noticed this lump a few days ago though at the time I just thought it was one of my chickens toes because she kicks a lot whenever I try to check her feet, finally got a good look last night and no idea what this is. She is a brahma so hard to get a good look between all the feathers. My first thoughts were possible ingrown feather and hopefully not a tumour. If its the former is there any sort of treatment? If its the latter is the only option to put her down?

It's likely a feather cyst. Find a sanitized razor blade and make a shallow incision across the top. If the follicle doesn't spring out, take a tweezers and free it. Spray with Vetericyn or paint Betadine on it or Neosporin after it's free.
