I have noticed one of my hens had swollen (almost like small bumps) near her beak and around her neck. She has bubbles and real sticky snot coming out of her nose. One of her waddles is swollen, she also has labored breathing, also mouth open trying to breathe. I thought she got stung by a few wasps, we found a nest near by. ( which I took care of) but now a few other hens I have noticed have some waddles swollen or bump like swollen under their beaks and some snot. One hen has her eye a little swollen. What is this? Is it infectious coryza? How do I treat or should I cull? Can I eat the eggs they produced? I am completely heart broken. I need honest advice.
