Ok I have three 7mo old leghorns. I bought them from a lady 3 weeks ago. Several days after I brought them home, one started to cough, sneeze a little, and breathe with her mouth open. Almost two weeks later a second hen started sneezing. Now they all three have runny noses and two have runny eyes. It's clear and there's isn't a smell that I've noticed but I could be missing it. The hen that isn't sneezing laid her first egg today! I've been giving them VetRX in their water so it will get on their beaks. They aren't as tame as my other flock so I've had a very difficult time in trying any direct methods of medicating. I don't know what to do..... I've been keeping them in an XL dog crate bc I don't want to risk my other 3 hens. I just am at such a loss please someone help...
