I've kept an eye on this hen since we realized that her bottom beak was growing faster than her top beak. She has always seemed to hold her own, has never seemed malnourished or ill. Yesterday, I noticed that she seemed a bit off, but since she and her little band are free ranging, had trouble catching her. We caught her today & I noticed not only that her beak is about 1/4" longer on the bottom than on the top, but she has a very large mush crop. When I picked her up, she drooled a bit. I put her in one of our little single coops with water only for observation. I know I've read crop info on here many times, but now that I need it, I can't seem to remember what to do?
