My husbands cousin in the UK runs a rescue for hens. She rescues them from battery farms though. Poor things look dreadful when she gets them but are healthy and happy by the time she re homes them.
I've had 7 hens die in the last 4 months and I now believe it is Mareks. I'm going to try this treatmnent for the next bird that gets sick and see how it works. THANK YOU!
