hi! I have a year old Australorp who suddenly developed wry neck a few days ago. she had a limp for a few months before but it was pretty mild so we left it alone, but now I'm thinking it could be related? none of the other chickens have had any problems. anyway I have been giving her vitamin e, b, and some high selenium foods. she's having trouble eating and drinking and looks like she might not last long at this rate so any advice to speed up her recovery would be appreciated! thanks <3
