I need to find the vaccine ASAP. I don't know if I can buy it anywhere other than ordering it online? I have no idea what to do. I have isolated the sick ones and every time I do they die. Two coughed up blood. I have tried everything. My husband and I just tore apart the coop (again) and bleached everything and we are letting it dry. That chicken doctor guy costs too much to talk to and there are no avian vets near me for a necropsy. I am weak from sobbing. They seem fine one day and then they get sick and die. They mouth breathe and stop eating then they suffer so much we cull them. I will NEVER buy or accept a chicken from anyone but a reputable hatchery EVER AGAIN. My husband did that, not me. I wanted to hatch my own. He is sorely regretting his decision to get some from a friend (although theirs seem okay) or an auction. The stools are fine, btw. Just a little eye goop, a gurgle, a honk, then dead. Eating and playing fine until 24 hours before. I never knew this could happen and I am heart sick. If anyone can help, or offer advice, that would be appreciated. I love my birds.
