I have a chicken with tapeworms. I have gotten two medicines from the vet. Now my other chicken has tapeworms. It is the middle of winter and cannot turn the ground as it is frozen. I have cleaned the coop everyday. They did have the greenhouse sunbathe in but I have since shut them out in fear that the soul was contaminated. I am worming my second chicken. Please tell me what to do since it is the middle of the winter. I only have 4 chickens and 2 seem to have them. Thanks
