I have a buff orpington hen that has a problem walking. She is alert and with no apparent injuries. She almost kind of squirms like a snake. If she tries to walk, she falls over. I have a flock of 40 or so chickens, and I treated them all using Wazine a couple of weeks ago. (My guinea birds battled round worms about 6-8 months ago and they showed similar symptoms, like being unbalanced.) She is eating and drinking, and I have her away from the other chickens, but otherwise, can anyone offer me any suggestions? Thanks! http://www.youtube.com/watch?v=V4WhADHIstw please watch this video..she didn't do much walking but I got as much as I could.
