Our Sulphur Crested, Gorgeous, who now has a collar on while a wound on her neck heals (Many thanks to all the people who kindly gave us good advice) has started doing something I have not observed before. She is drinking more liquid than normal, then masticating with her beak and tongue, and producing a white froth. I am not sure whether she is working up saliva, or regurgitating liquid. She then
rubs the white foam on her feathers, and when it dries the feathers are crusty and hard. I don't know whether this behaviour is because she cannot preen in the normal way, or whether she is getting sick and I need to get her back to a vet quickly? The collar has been on for 8 days now. A fresh collar is fitted every day, after coating the wound with anti-biotic gel. The wound, though large appears to be healing, and she is eating, though she is more subdued than normal. I am alarmed because I do not understand the behaviour. Has anyone seen this happen before?
