I had a hen that was slowly dying and in the morning was dead. Nothing obvious although I didn't examine her closely. Laid quite for 24 hours then died. Any idea? Friend says that's what happens when bitten by weasel? I though I could only wait and see if I had any other problems. Don't know how old this hen was, might have been older than I was told, sometimes that's the case if they want to be rid of them.
