I live in Portland, OR in an urban setting. My Enriqueta (my plymouth rock) was just killed by something (I think it was a cat) that broke her neck. We have had racoons but we have not seen them in a while. She was out with Florentina (my buff orpington), and something took her. We found her next to the fence by the corner. Something had crawled in from the the other side. We found lots of feathers, but other than her neck, she was intact. Could this have been a cat? We have cats at home, but they were not outside, and they've never attempted to even chase them. I'm also wondering what's next for our remaining chicken. I've read plenty about introducing chickens to existing flocks.. but didn't find anything about having one chicken left. Will she get lonely??? I need help with this question, more than anything. If you have any links or suggestions, I would very much appreciate it. Florentina was the lowest of the pecking order, she was born around May 5 along with my other two chickens (both dead now). They were all laying eggs daily... I'm so shocked, that I don't even know what to say. Please, help... I know it will take time, but is introducing two other chikens worth it?
