My flock has been showing symptoms for a while now, I’ve tried all the natural remedies I could find (ACV, Garlic) as well as vetrx in their water. It seems to help for a day, then it’s back to normal. Symptoms include sneezing, open mouth breathing, bubbly eyes, deaths in a few, gurgling (rooster especially). On another thread I read about denegaurd, which I’ve purchased and am waiting for it to arrive by mail. My question is, how young of a chick can have that? I have 2 salmon favorelles (hatched 2 days ago) under my silkie, who has now started to show symptoms as well. I’d like to treat the entire flock (about 50) including the babies if possible. Yes I know it won’t cure them, only their symptoms, I have a now closed flock due to this and just want them to be comfortable until they pass of old age here at home. I considered culling but can’t bring myself to kill so many birds just so I can have more come and go. Help, opinions, share your experiences please!
