Hi, My name is Sally and I live in Barnstaple Devon UK. I have been keeping ex battery hens for 9 years. Unfortunately these poor girls are quite worn out when I get them aged 18 months so they are prone to illness. have lost 3 recently and am now down to 2 girls one of which is very poorly. My vet suspects Mareks but is not sure. I have been using the Forum to try and get ideas of what I can try to help her.
