Mix a little bit of olive oil and water together in a small container, ( just a little bit, but make sure its got the 'oily' feel to it )
take a small syringe and give it to her by mouth. Don't stick the syringe IN her mouth but just squirt a little bit in her mouth at the tip of
her beak and she will swollow it. Next gently (VERY GENTLY) masage her crop, don't push on it alot though because you don't want her
throwing it up. Most the time you can feel the food in her crop breaking up after masaging it for a minute. After your done with that let
her be, and check it in the morning, You may have to do this for a couple days. Good luck!!
