My brown leghorn stopped laying recently, I had no idea why. Today I looked at him and he seemed to have a massive breast growth. So I felt it and it seemed to feel like play-doh or clay. When I took my hand off the hand-sized lump, MY FINGER IMPRINTS WERE MOLDED INTO IT. It was a giant lump of something clay-like. Does anyone know what the heck it is? Im really worried!
