It looks like this. Now that I know they're babies I'm going to put a big cardboard box inside coop and keep them in that with heat,food and water. How long should I contain them in box? Until they start jumping on ledge? Now that I know they're babies do I add sugar to their water or electrolytes when they first arrive?
Thank you
If it doesn't have instructions to use it as a brooder plate -- which should include minimum ambient temperature information -- you can't trust it as a heat source for chicks.
With plenty of space to provide safety clearance, a secure means of hanging it (wire or chain, not the stupid clamp), and room to have the warm area and the cool area there is no reason not to use a heat lamp.
They are inexpensive at your local farm supply, where you can also buy a bulb that does NOT have a teflon coating.

The 250 red bulb is the most commonly used. I used lower-wattage reptile night bulbs to brood in warm weather. My lamp hung from a chain:
Having nice, large facilities allows for plenty of safety clearance.
