Can this be related, or is it likely coincidental? Yesterday, I treated my four hens with Wazine 17 (1 oz in one gallon of water for one day). Today, the oldest one, an almost 6 year old Buff Brahma, is stumbling a bit and seeming to have poor balance. She also appears to be limping a little. It's a little hard to tell if this is more a balance issue or a problem with her legs or feet. She does have scaly leg mites pretty bad, which we have been treating for the last couple weeks by oiling her legs, but I admit we haven't done it as often as we should so it is still an issue. No signs of bumblefoot, though I removed two from her last year. I have her in the house and she is alert and eating well. Poops are a little runny. I have a perch in the crate with her, but she is choosing to lie down instead. Breathing is very slightly wheezy, but this is only noticeable when I had her wrapped up and held upside down to look at her feet after soaking them for a bit. I know Merek's is a consideration with balance issues. But isn't it unlikely at her age? Two of our girls were added to our flock on Nov 4, but none of the other girls have been sick or showing any symptoms. So I'm wondering if the could be a reaction to the Wazine. When I took the water with Wazine out yesterday, she seemed to drink more than the other girls, at least while I was out there.
