Pretty sure this is an older injury. There is no fresh blood. She was jusy holding really still hoping i wouldnt throw her out of the nest for being broody. I saw the crack at the head side of the dark spot and decided to leave her be until I got my phone. Turns out she was "using the facilities". Took the picture while she was drinking. Is there anything i can do to help her heal or will it be cracked for the rest of her life?
