BABY ZEBRA FINCH

Question
HI, I HAVE A 3 DAY OLD ZEBRA FINCH THAT THE PARENTS WOULDN'T FEED (IT'S THEIR FIRST CLUTCH) SO I HAVE BEEN HAND FEEDING IT.  IT IS DOING REALLY WELL BUT IT KEEPS GETTING AIR IN THE CROP.  LIKE A LITTLE BALLOON.  I CAN BURP A LITTLE OUT BUT I'M SCARED THAT THE CROP WILL POP, IS THERE ANY THING ELSE I CAN DO?  I ALSO HAVE A FRIEND THAT HAS ZEBRAS THAT HAVE EGGS READY TO HATCH, IF I CAN GET THE BABY TO SURVIVE LONG ENOUGH SHE IS GOING TO FOSTER IT WITH HER ZEBRAS.  THANK YOU FOR YOUR HELP

Answer
Hello, Dont push on the crop you'll pop the crop and kill the baby, its ok to have some air in the crop my baby budgies did when I was handfeeding they turned out fine were healthy and were sold. Yes it might be able to be fostered with her finches as long as he isnt hugely bigger/older then the newly hatched finches.
