I start off all of my hatched chicks on what I call "chick baby food", which is just their crumbles make into mush with water. Anyway, the youngest babies in there are 5 days old now and one of them does NOT want to eat the crumbles. I've started weaning them off the baby food and trying to get them to eat just regular food. The one chick has been whining all day and its crop seems empty. This is the first full day with no "baby food". Will the chick eventually eat it and do I need to just wait it out? Or should I feed this one mush separately until it's ready to eat solid food only?
Here's the culprit, the smallest chick of the bunch.
