My three chicks are 7 and 9 days old. Live inside on wood shavings and only have eaten chick starter. A couple seem to be getting really full crops. They have plenty of fresh water. I am nursing back one chick that had a really large impacted crop from yesterday. It was gone this morning, so I let her eat and she wanted to gorge herself also looks like it's uncomfortable to swallow. (Maybe from syringe yesterday?) Well her crop fills up so fast and starts to make a lump again. Is that normal? I'm paranoid now. After working with the chick for 14 hours on and off I don't want to start it up all over again. Someone mentioned adding small grit is that something I should be doing??? HELP!!!!!
