My Easter Egger Jen has been acting weird for the past couple days...She seems distant and sits in the coop while I let the flock out to free range. She seems slow-moving but has no visible problems with her health. She looks perfectly healthy but just isn’t being herself. I don’t know what else to say but I’m wondering if maybe she’s depressed, stressed, or something worse? Like a disease or illness? If anybody could suggest some diseases or what might be wrong, I’d be very grateful!
