I just noticed my four-year old SLW Lilith has some weird black scales on the front of one of her legs. On close inspection, the black is slightly greenish around the edges. She seems to act and feel okay. Does anyone know what this is from? It's not easy trying to photograph (with no one to hold her) a hen who's built close to the ground. I had to pull the leg out from under her while juggling the camera. I hope you can make out the unusual scales.
