I have 4 new sebrights that are with 3 mixed breeds, all about 3 weeks old. Only the sebrights are having issues, their eyes seem to constantly be closed, the walk a little crooked and today I had them outside and then when I picked them up to bring them in I noticed they have a crusty type of discharge on their wings where they meet their body. They seem lethargic and just blah...I don't know what to do. I didn't see any mites, no worms in their poo but I didn't look too closely. Any ideas??? I can try to get a picture....
