Hello! I have 2, 6 year old Russian orloffs that have been having balance issues for a couple months. I have tried everything I can think of : vitamin b 12, nutri drench, higher protien, electrolytes, rooster booster, dewormed, sprayed for lice. And it just isn't helping them. They can walk a little bit but with this cold snap they even lost that ability. They just stand propped against the wall. The one still has a decent appetite but the other doesn't at all. I have not been able to find a vet around here that will treat chickens unfortunately and am wondering if anyone has any other ideas. I lost their other hatchmate last year to what acted like merricks but none of the rest of the flock got it so I'm thinking it was something else. I don't know if this is just a bad line and they've lived as long as they can or if something is genuinely wrong. Ideas?
