I have a broody Maran that I removed from the nest in order to get her to start laying again. I just happened to notice a strange, hard growth coming directly out of her chest - literally poking through a hole in her skin. Underneath the skin, there is a larger area of hard growth, and it is painful to the touch. The skin around the hole is completely infection free - like a peirced ear, only larger. However, under the skin it is blue - and a scary green. Could it be gangrene? It seems to be attached to her breastbone - like a strange bony growth that popped out of her skin as opposed to something that got lodged in there, but I could be wrong. I wondered if it may have anything to do with her sitting for well over a month now on wood (she moved the straw out of the way and broods on the wood) trying to hatch non-existant eggs. Anyone encountered anything like this?
