Two weeks ago, I found a hen hunched up and gasping and choking and sneezing blood. Her eyes had junk in them and cheesey stuff started coming out her nose. I separated her and the next day found three more young pullets/cockerels having stuff in their eyes, but not sneezing. A few days later everyone was all better so I put them back in with the flock. In about 4 hours I went back down to the henhouse and 5 more had it, then that night i rounded up 2 more and put them up in a separate coop. the next morning a rooster got it, so he went up too. a few days later about 10 of them were sneezing (which is one of the symptoms of what they have, coryza). I instantly knew that I should not bother separating them and that everybody has it. sure enough right now every single bird has it. two days ago a black sex link passed away and i have a feeling some more are following after her. From what I believe we have CORYZA. I would like to treat it naturally, but in this case I am willing to do whatever it takes to make them better. please do not say to cull, I will NOT cull, i want to know how to save them, not kill them. If I wanted to kill them they would be dead right now. Thank you.
