My neighbors may have been fighting roosters. I was not aware of what exactly was going on but went over to ask about their chickens. To my surprise they had 6 roosters and 1 hen. I now have the poor hen who seems to be over weight and unhealthy. Since I am new to this I really need help in caring for her. I have her secluded from my flock for the time being. I have added raw apple cider vinegar to her water and gave her some feed. I am at a loss of what to do now though. Her vent is dirty but I am not sure what to look for exactly when it comes to mites and such. I let my flock free range in my back yard during the day. I do not want them to get sick. I feel like I should not let this new one in my yard but I also do not want her cramped in a tiny kennel. Please help I should add that the police and Humane Society have already been involved and these people were given 30 days to get rid of them.
