I have a chicken that's around 2~3 months old. It already appeared to have some sort of foot injury so it was always walking in like a goofy way, but it was always active, eating and moving around, I don't know if that information relevant or not but the past 2 days or so it hasn't been moving nearly as much and today it's barely moving at all. it's continuously doing some sort of breathing motion. It doesn't appear to be lethargic like it's eyes are open it's not sleeping while standing or sleeping at all during the day as far as I noticed it's just standing in the sun doing the same sort of breathing motion while almost completely still, occasionally eating a bit but only a tiny bit. I can send pictures or videos if you need to see anything and thank you
