Urgent - is this coccidiosis or dehydration/malnutrition in chicks?

[Froh]

So, some of the chicks have been more actively eating on their own, and they all much prefer to eat out of my hand than the bowl for some reason.
They also prefer to be huddled under a heat lamp and some of them sleep on their sides (or just don't get up after falling over), whenever I panic and check to see if they are still alive they would just wake up with a tired look and would not stand up until I position them so. If I placed them down sideways they do not bother getting up, and those ones in particular feel much skinnier and boney. Since I can't give them nutridrench right now, what can I do to help them get an energy boost or make sure they have an appetite? Sorry if these questions are redundant, I just have no idea which foods are off limits during corid treatment.

There are no foods off limit with Corid.
Feed them chick starter. Make sure they have grit available.
They need fresh air and access to sunshine as well.
