So my roo wears a no-crow collar (not making that mistake again) and he got it caught on something and was choking. I don't know how long his airway was restricted for, but it wasn't totally restricted. He had very little color in his face and the tip end of his comb seemed to be turning blue. (That color is coming back now.) We got the collar off and now have him isolated in my bathtub and he seems to not be doing so hot. His airway seems clear (I shone a light down his throat and got a really good look) but he is extremely listless, lethargic, and seems to be falling asleep with his head tilted off to one side. His breathing seems to be a bit slow. He is responding to sounds (especially the chickens outside squabbling) and sights, but not really moving a lot. Any thoughts on what I could do for him? Should I let him just breathe and rest? He has a chick dish of water in the tub with him too.
