Nanday Conure with an Itchy Beak
I have had my Nanday Conure since he was a few months old, for about ten years. Today I noticed he is grinding his beak against anything he can(this is not the casual wipe his beak or small scratching like he does after he eats) he is using the sides of the cage or his perches. So I took him out of his cage gave him a bath and then helped him preen as I usually do for the feathers on his head and neck that he can't get to himself.
As usual he enjoyed it and layed calmly in my hand while I was doing that. Once I put him back in his cage he started with the gringing. He even put his beak thru the cage and I was just rubbing my finger by his nostiles and down his beak and he calmed back down. What should I do to help him?
