So I went out to check on my chickens and I found 1 dead in the pen. She is almost a year old and 1 of my best layers but she had what was like pasty butt. It's been better...no problems the last month or so but when I found her her foot had intestine wrapped around it???? What could've caused that??? No blood today and she layed an egg this morning. She's a top hen. Never been bothered by the others and nothing got in and attacked her? Any ideas???
