Today I was cleaning out my birds cage and I saw that my hen's droppings were full of blood!!! Does anyone know what is wrong? Lately I have been putting vitamins for breeding in her water and I thought maybe bacterial growth from the vitamins could have been the culprit, but I change her water every day. Is that enough? Also they (the hen and the cock) have been sneezing a little bit. I know they stick their claw in their nose to cause a sneeze but they haven't been doing that. I looked but there seems to be no discharge. What could it be??? I guess I'll have to take them to an avian vet if they don't get better.
