I have a 4 week old chick. It seems that her crop isn't emptying overnight. Yesterday for 12 hours I only gave her water and Olive Oil. Then would massage her crop. It doesn't seem to have helped. then yesterday afternoon and all day today all I have fed is Yogurt, Hard boiled eggs, and rice along with olive oil. I don't see any change but my main question is should I still be giving her grit?
