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

[Froh]

Don't give Nutri-Drench or vitamins while using the Corid.

Don't feed medicated feed while using it either.

You have been feeding them medicated feed already?

Yes.. they were switched to the Manna Pro medicated version this week, and that is currently all we have, other than scratch grains for the older chicks and chickens. Which one would be better for them, if we currently have no other options?

Edit update: Just came back with corid, they seem more active eating and drinking after some nutridrench
I swapped out the water for corid mixture and they are drinking with no problems. I also checked the packaging of the Manna Pro feed, and nowhere on the packaging does it mention being medicated, however the same packaging on walmart claims so: https://www.walmart.com/ip/Manna-Pr...-Starter-Crumble-Chicken-Feed-50-lbs/43924108

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.
