My sons friend is a tree cutter, they cut down a tree this afternoon, then 4 babies came crawling out of the nest hole half way up.
He brought them home not finding the mother nearby. I think they are grays by the size of them in his video and moving around alot. They look a good size, no fur yet but eyes are open now.

He has them in a box in the house for the night, next to a radiator heater. It is cold enough outside tonight, about 27 degF. The mother must be frantically looking for them if she's still alive. Shouldn't he try to find the mother again tomorrow ?

Any ideas what liquid he can give them tonight ? Nobody has esbilac at this time tonight.
