Baby chick's probably shouldn't be held. Many will die from shock just from fear alone. 90-95 is the temp they should be at. Next try, get a heating pad, remove the cloth cover, form a flattened bridge out of wire, lay the heating pad + a layer of bubble wrap or thin foam packing over the top of the bridge and wrap the bundle with plastic wrap to secure it and keep it clean for next hatch. The angled bridge allows smaller chick's to go to the lower end, larger chick's to the larger. The height should be just above the shoulders, and there should be space in the brooder for them to run out, get a drink or a nibble and run back under electric momma. I have bent my wire frame with legs an have 1/4" + 1/2" wooden risers with a hole drilled so I can adjust the height as the babies feather out. Read up on how / when to decrease the heat from 95->75 over the time in the brooder pending your chick's, as quail, chickens, ducks have different maturity rates.
