I got my Amazon about a month ago and didn't notice at the time but one of his nares was closed over with a film of dried mucus. I have since softened and removed it with coconut oil but it still has a clear drainage at times and tries to do this again. It's not very bad drainage but I'm concerned it may be an illness of some sort. He also had a good amount of regurgitation. It's this a normal parrot thing? I know most birds do this some but his seems excessive. We do not have an avian doctor in our area so I haven't taken him to one. I have read that drainage can be caused from the regurgitation which can be from a vitamin a deficiency. In giving supplements and feeding as much greens as he will eat. He is acting completely fine health wise other than this. Any suggestions??
