I just noticed yesterday that one of my hens is missing the top of her beak. I'm not really sure how long it's been this way, but I think I would have noticed it before now if it's been that way for very long. She's not usually a friendly bird, but the last few days she's been running to me when she sees me outside. After I noticed that her beak is partially missing, I can't help but to think that she is trying to ask me to help her in some way. I have so many questions. Will it grow back? Should I feed her differently? Should I trim the bottom of her beak so that she may be able to drink better and peck better? Any advice would be greatly appreciated!!
