I lost 3 of my beautiful hens to Mareks a few months ago. My Isa Brown has survived, but doesn't look totally recovered.
It's been a few months since the others died. Wondering if it's safe to get more or will they die from contact.
I, too was devastated to loose my hens. First the bantam and then the Isa Brown and then my beautiful Orphington.
Am left with just one Isa Brown, she doesn't look good, seems to make a crowing motion and looks lonely.
The guy I bought them from said they had been vaccinated, but he wasn't sure...
