Hi everyone....I have a 2 yr old chicken who is not not doing well - please can anyone help. She is consistently picked on by our large drake as our chickens and ducks are in together....about a month ago she started to just sit on her own so I separated her - after a few days she perked and went out - I thought she'd just had a bad peck or something. Since then she has been OK but still keeping herself to herself when she can - often prefering to stay inside on her perch when I opened the coop up in the morning. 2 days ago she came out and was limping and weak so I separated her again and she waves her head from side to side now when she sees me. I haven't seen her eat for days so today I tried her with some ham to tempt her - she shuffled over and tried to peck it but kept missing, like she can't see the food properly. I am thinking maybe she has had a head injury but I have no idea how to help.....does anyone have any suggestions?
