I don't want to speculate as to the fate of the baby, the corrugated sheet metal had to be moved and it was only a few minutes after I had removed it that we heard the squeaking. Nature is gonna nature, either the squirrel will survive, or a predator will get an easy meal. The thing is, within the family, we will probably ask "is that the squirrel all grown up?" every time we see a squirrel up there for the next few years. I think that's the best outcome we can hope for.
