the foil should be safe.Just a thought, what is in the middle of the insulation board? If it is anything that is fibrous and carcinogenic there might be some danger to the chicks if they eat or breathe it. Just a thought. I'm no expert but I had a cat that sleep on one and ended up dying from it.
given the time the chicks are in it I would not worry. Its not like your cat sleep in a styro box
its a decent temporary brooder.
