I didnt have any luck searching this topic. I noticed this morning that one of my 23 wk old Red Star's beak has a layer that is lifted & popped up, with what looks like strong, new beak underneah. It's only half of her top beak... mid to tip and one side of this lifted layer is still conected to the left side of her beak. There seems to be nice, hard, yellow beak material underneath. Needless to say, as friendly as she is.... she won't let me touch it! Thanks!
