My new gc conure (he's 4 going on 5 months old) has begun sneezing about 6 days ago but it started being more frequent 3 days ago. He was really sweet, no biting the first few days we've had him, except the first 2 when he was new to things. After some time and coincidentally or not, when my grandfather visited he began being very aggressive which I though was because we had a guest that was annoying him, but his aggression spread to me and my mother.. About 6 days ago also, he started scratching his face INTENSELY but he is preening his whole body, still 60% he has a foot up his face so that's weird.. So to sum up 6 days ago he started scratching his face and sneezing (I first heard him sneeze after he took a bath) and about 3 days ago he started being so aggressive that in the morning we can't have our hands close to him or he'll bite them off (he chills out in the evening). I don't have an avian vet in town and we've had him for about 11 days so I don't feel good bringing him after such little time. What should I do? (He has an okay diet, fruits, lettuce, oats, seeds)
