Really? OK, firstly…why would you want to? Secondly…wouldn’t that be a bit gross? I don’t think you can with rice although eating dry rice might make them quite uncomfortable if it expands with the liquid in their stomach.
I remember reading somewhere once that you could blow up seagulls with certain things because birds can’t burp. So if you feed them something that generates a lot of gas in their gullets, that could have very bad side effects for them. Bit cruel though really.
