My chicken coops sound like a TB clinic!!!! I'm on day two of giving all hens and roosters a Tylan shot. Easter- my sons rooster is in crate on front porch away from others. His eyes and nose had copious drainage. The rest are just congested and wheezing. So far we had to cull four that were suffering really bad and found one just dead. Its hard to tell how each one is eating or drinking. I've been syringe feeding Easter watered down oatmeal with applesauce. I've been putting the same out in the different coops. So- is there anything else I should be doing? Should I give the shots for three days or five???? I'm new to chickens so any suggestions are welcomed
