I came home last night and one of my 9 wk old Buff Orp girls was missing. I searched all over for her last night and this morning. I let them free-range during the day and I was worried that maybe a predator had nabbed her. Well, at noon today I happened to notice that a little 1 gallon bucket that my son had left in their yard was upside down today and it hadn't been that way yesterday. I tipped it over and sure enough she was under there dead. I can only imagine she must have tried to perch on it and tipped it over onto herself, the poor thing. I just feel horrible. Live and learn I guess. I'm going to start doing a better job of baby-proofing the yard now.
