Wondering what on earth could have happened to her last night. It did not freeze so she couldn't have been too cold? It looks like she dropped dead right off the roost last night. So sad to find her this morning. No obvious signs that I can see. I am a new chicken keeper as of last spring. Penelope was one of our spring chicks last spring. Maybe I am too novice to have notice any subtle signs. All the chickens (we have five) have been very healthy (seemingly to me!). We are sad to see her pass. I hope I can get to the bottom of this so we don't have any one else go. Thoughts on what this could be. I don't think she was egg bound. Five chickens, five eggs a day coming in. No sign of parasites. They all LOOk so healthy. Bright combs and waddles. I have not begun a worming schedule yet. Planned to this spring. Was it an oversight to wait that long? We have been using a heat lamp on them when it gets below freezing at night. I hope doing so isn't a mistake. Could we be messing up their bodies (heat) regulatory abilities?
