Can hens hallucinate? she was a chick in the spring and has been doing fine. yesterday she didn't drink or eat when i brought out morning supplies. she was acting odd. My chicken don't let me touch them but i started to stroke her and got no response so i picked her up and put she in a small seperate cage and got her to drink and eat some. she napped on and off all day. She also has (i'm not sure how to describe it) floating head, it is always drifting, and like she can't see. By late afternoon she seemed fine so i tried to return her to the group and the older 2 hens started to pick on her, she is back in the small cage and pecking at nothing and still acting odd???? any thoughts???? I looked around on the threads, being new i don't think i am utilizing the sight the right way.sorry!
