Had 3 chickens at the start of winter. One passed we think due to below freezing temps. We just lost our second about 3 weeks ago, we think a hawk got her. Now our one and only seems a bit off. Almost depressed. She isn't laying. doesn't go in her coop at night, and is hanging out on our deck instead of grazing all day. We can't get any new chicks for a while because we are in the middle of a move. Is she lonely? Will she survive? She's acting really bizarre and I'm worried.
