Well, I found a couple of lumps of sticky seed on the side of his feeder. I smelled them, but no odor. Later on, he pumped his head violently, several times, and that is when I saw the mucus. After that, he was quiet and fluffed out for awhile -( actually, he had stopped chirping when he started the regurgitation). I heard him make several muffled chirping sounds and then, he started his regular chirping routine. He's out in the living room now, chirping up a storm. If I remove the millet, how long should I wait if he doesn't eat his regular seed? He went to the vet a couple of years ago after a stint in the wild - he had gotten out of his cage and flew away. Was gone for 3 months. Vet said he seemed okay after such an ordeal.
Thank you. I feel like I have a place to start anyway. He started to take a seed from the feeder this morning, but put it down, very odd. He ate egg stick and a few greens though. I guess I'd better find an avian vet.
