We got a Silver Duckwing Bantam Roo, Cogburn, on the evening of 12/14. 2 days after we got him, he started showing signs of what I can only assume is a Respiratory illness. Clear liquid coming from his eyes, nostrils and beak, though seemingly only in the afternoon/evening? In the mornings and throughout most of the day, he eats, drinks, crows, and has clear eyes and airways. He is co-owned with a friend, who feels that Cogburn is going through separation anxiety, and has asked that we put one of our Banty Duckwing hens (also co-owned) in with Cogburn. To be honest, I thought yesterday was curtains for the little guy, around roosting time he had so much goo coming out of his mouth and nostrils that he horribly sounded like he was drowning in it. It was tremendously upsetting to both Cogburn (obviously) and myself. I have yogurt in there for him, and have been adding ACV to his water and he's staying the back room of our house, so he's nice and warm...but I really feel like this an infection of some kind, and am beyond hesitant to put a healthy chicken in there with him. Especially as it will eventually raise the question of infecting all of my hens even if Cogburn and the hen in question do survive...because we will need to put them somewhere. Ugh! So, I guess my question is...does anyone have any input? I couldn't find an obvious precedent online for the separation anxiety theory, though I do understand that they are flock animals and don't like going solo like this. And I'm not sure why right now he seems completely healthy and relaxed, if not maybe a bit lethargic. But later today I'll probably be near in tears again watching him fight to breathe. And lastly, would it stress him out more to add a bird he's never met to the small quarantine enclosure? Thanks so much for reading, anything input/thoughts would be greatly appreciated!
