My birds all love gloop from the budgies to the cockatoos - sheesh!, even the passerines (canaries, finches, cardinals) do! And I've never had a problem switching them in a matter of days. There was only one bird that refused to eat it and would wait all day long for her seed dinner: Piquito, the quaker. I kept her in her quarantine cage long after her quarantine was over because I use this time to switch them so I know that, when I let them out, they will be eating what they are supposed to. But, two weeks went by after the usual four of quarantine and she was still not eating it so I let her out (I hate to see animals in cages) and, lo and behold!, she started eating it as soon as she was free! She was just depressed from been caged all the time and was eating just enough to keep body and soul together, the poor thing! As a matter of fact, she likes it so much that she always steals some from the big bowl where I bring it into the birdroom before I have a chance to serve it on the paper plates I use
