Yep, and he's feeding it to Archie. Is this normal behaviour? Yogie is about a 1 to 1.5 years old and Archie is 4 months.
I could tell because Yoges ate, and then pumped his body up and down rapidly with his beak open before 'frenching' Archie. The pumping motion was the same motion he used when he vomited on the day we got him.
