I don't know if this is normal, but my 7yo rooster seems to have a lot of saliva, he has had a lot of saliva for a while, I don't know when I noticed all the saliva. He is acting normal and otherwise seems fine. When he eats it seems he has trouble swallowing the food, and sometimes drools. The food he eats is in pellet form. Today when I put him down after holding him he vigorously shook his head a couple of times, that was the first time I have seen him do that. Does anyone know whats wrong with him? I will try to get some pics soon.
