My hen Beryl was diagnosed with possible egg peritonisis - she has fluid in her tummy but was eating normally. She was given antibiotics - Amoxyclav. Then the vet rang to say she had coccidia in her faeces sample, although she has no symptoms of coccidosis. So she gave me Baycox. I didn't give it immediately as it was very hot weather. She's been taking the antibiotics for 5 days and has been looking sick ever since I started the antibiotics and becoming more bloated. I began the Baycox in their water last night and overnight she had bad diarrhoea. This morning she is so weak she can barely walk. She is dehydrated. Should I stop the treatment of Baycox for all the hens? The others don't have diarrhoea. Should she have even been given Baycox as she has no coccidosis symtoms apart from the coccidia in her poo? Should I see a different vet? I travelled to see this lady as she is a chicken expert but she was not very keen to explain anything to me.
