Hello, so I was wondering, have any of you had chickens that have shown signs of depression? I know it's a weird/dumb question, but I'm kind of worried about my Polish Cockerel. He used to be a really outgoing and mischievous chicken, always getting himself into trouble by escaping the yard and acting like a punk towards the other chickens. Ever since his brother died though, he's just been so... I don't know, sad? He looked for his brother for about a week straight (they were partners in crime) and then he just stopped. He just sits in the same few spots all day long, and has gone from the middle of the pecking order to the bottom. It's a sad thing to watch, maybe I'm overthinking all of this, but I just really feel like he's down in the dumps.
