Hello! My four new layers are about 2 - 2.5 months old. One has been sneezing for a month now and another has been sneezing for a couple of weeks. Now it looks like my roo is sick. He’s making a weird wheezing noise and keeping one watery eye closed. (One of the hens has also had an occasional watery eye.) What could be causing this? I don’t want to integrate them into my flock until I get them back to full health. Thank you!
