I found my hen this morning with her head between her legs and got her head up. I have gave her two doses of vitamin E and baby vitamins and scrabbled eggs. I feel like she has shown improvement. She will be walking around fairly well but all of a sudden she will walk backwards and her head will fall back down and I've also seen some twitching. I thought her crop was compacted but now it feels more like a hard mass. Any ideas what could have happened.
