I wouldn't worry about it I was worried too when I got my 3 day-olds. I'm pretty sure I had a crop impaction in one of the chicks though, but adding apple cider vinegar to the water, removing food for a day (except for yogurt and olive oil), feeding olive oil drops by hand and massaging the crop fixed it. She is now a robust, healthy hen. It may have gone away on its own but I didn't want to take any chances.
Another one of the chicks stopped growing at one point and seemed to get really weak, and I thought maybe it was coccidiosis so I switched over to a medicated feed for a while. I don't know if this did anything, but she is alive and fine today if a bit on the scrawny side (I'm back on organic feed now BTW).
Chicks are pretty hardy and I would definitely recommend raising day-olds.
I would just recommend adding apple cider vinegar to their water (1 tbsp vinegar/gallon water) as an all-around preventative health measure, and supplying them with chick grit to avoid crop impactions, and things should go fine.
