I have a brahma hen that i realized a while back she was having trouble eating, and saw her beak was overgrown. I trimmed it and that helped some, but over the course of the past week she has been eating less and less. I kept noticing mud caked in her mouth. Today she was sitting in my lap and I realized she couldn't really close her mouth. I took her in for another trim and this time noticed her top beak's sides were curling under towards the midline of her mouth. Essentially the bottom jaw could not fit into the top jaw. I trimmed away the curled bits, scraped out the mud, and she is doing better but not perfect yet. I'll probably have to make a few more adjustments. I can't see the quick when I'm trimming, so it's a bit dicey and I'd rather go slow than take off too much. I really wish I could find a good graphic online of how this shape it properly but haven't found anything good, mostly debeaking info. If anyone knows a good picture that shows the proper cuts for top and bottom beaks it would be much appreciated if you share!
