I had a hen that was gurgling and sounded like she had pneumonia. she was breathing through and open beak, so I gave her some clavamox that I had and she seems much better. I had isolated her, but now it seems that I have some other sick, coughing hens. One had thick, white, sticky stuff around her vent (but it didn’t seem like vent gleet) and I noticed that the eggs that I got today seemed to have a weird, goopy coating for them. I’m new-ish to chickens and have no idea if we have a chicken vet anywhere nearby and I have no idea what to do. Can I put something in their water to make all of them healthy again?
