My 5 month old cinnamon green cheek is as active as ever, eating and drinking well! A bit grouchy right now due to his molt but doesn't puff up or anything, still grinds beak every night before he sleeps. He seems happy and healthy but as I had him on the floor of my room with me tonight, he started rubbing his head and his back against my thigh and arm and kept doing that then threw up this sticky white odorless goo... I will call his avian vet tomorrow to make an appointment just in case it is vomit.. what do you guys think? Please help. Thank you
