Goose throwing up????!!!!!

[Scullysk8s]

Hey all, something really weird just happened with my goose Ryan, he's about a yr and a half old Canada goose. I was just making him his dinner, duck feed, a little cracked corn and oats and I topped it off with some meal worms. He gets that for dinner pretty much every day. I set it down and went to the kitchen. I heard him eat and he walked over to the kitchen where I was, looked down and a clear mucusy-vomit like liquid poured out of his mouth!!!???! He tried to then eat it back up. Shook his head and I shooed him away and had him drink some water. He seems perfectly fine and has had no abnormalities in behavior other than that random like throw up???

Please does anyone know what that could've been??! Why? Is he going to be okay?? What could have cause it so I can make sure it doesn't happen again. Or is he sick??!! help please! Ty!!
