If I were you, I'd give individual bolus of Nutridrench to any chick who needs it (via syringe). It's basically molasses and vitamins/water, so there is a sweetness to it that encourages them to eat it, I think. Then put the Quick Chik (electrolytes and vitamins) in the water for the first few days. you can put a container of clear water in there also, or follow the instructions on the Quik Chick. For instance, I have Hydro Hen, which is electrolytes and probiotics, and it says feed for 12 hours, then 12 hours plain water, then you can feed again.
I don't think there's any need to feed glucose. Best to let them eat the chick food. One thing I would do though is give them some probiotics. you can put that in their water. It will help their digestion. Their poos are so watery generally, I fed probiotics periodically just to make sure everything was working properly.
I found when feeding Nutridrench to a 4 wk old egger, you don't have to put it very far into their mouth. I would dribble a drop just below their tongue, and then let them swallow it. Even holding the chick a bit sideways, and dropping the nutridrench on the side of their closed beak where it dribbled in a bit was enough for them to swallow it. So kind of see what works best for the size/age of chick you get.
I had a 4 wk old egger brooding in a warm/hot garage who had been stepped on and had an injured leg and could barely walk, and therefore hadn't been able to drink for an unknown period of time (probably a day - she was fine that morning, I found her in the evening), and I alternated Nutridrench and water in syringes until she wouldn't take either any more. But she was happy to drink both. I actually didn't put electrolytes in her water, because she was acclimated to the garage temperatures, and it's cooler in the evening. I figured once she was drinking and eating on her own, she'd be okay, and the Nutridrench helped that happen.
Not quite the same as shipping stress on day old/3-day old chicks, but a decent example of a stressed, hot, dehydrated chick and how I was able to successfully help.
