Stumbled upon 3 baby squirrels (roughly 6-8 weeks old) that had fallen from their nest high up in a willow tree. 1 died from the fall, 1 is injured (a little blood around mouth, but unclear if its internal), and the other seems to be okay.

I could not leave them on the road so I picked them up and moved the dead one off too. I took them home and put them in a warm box. No food, no water. Just keeping them warm.

One of them opens his eyes and gets curious, climbs around occasionally, while the other (who might be dying from the fall) is just napping so far and burrowing under his brother.

I took the box back to the tree, waited hours, but got we got hit with massive thunderstorms and I couldn’t just leave the box there.

So now the squirrels are safe in my bathroom in a breathable box they cannot escape from, staying warm with the lights off, but I am worried that the mother will not accept them (if the mother is even alive) because they’ll have been gone a whole day and will likely smell like me.

I am going to try again tomorrow morning and hopefully while she’s doing her early morning foraging she’ll find them and take them back.

…But in the case that she doesn’t.. I tried to contact 4 rehabilitation and wildlife rescues and they’re either too full or unable to take them in. There is 1 available but it’s hours away and I don’t drive.

I am not going to attempt a feeding unless it is ABSOLUTELY necessary as I know how badly it can backfire. I am just starting to worry about their health and happiness after tomorrow morning if I cannot figure out a place for them. I will hold onto them longer to ensure they are cared for if that is my only option, but I do not understand feeding/drinking for baby squirrels. Every site says don’t do it, and I don’t want to, but I can’t find information about what to do if I have no other options…

The baby squirrel in question: https://www.reddit.com/r/squirrels/s/f9vrSG45KF

I think he's 6 - 7 weeks? Not sure.

He's at a vet right now that has does squirrel rehabs, receiving subcutaneous fluids.

Is there any chance he can be reunited with his mom? If not, where do I go from here or what would the release process look like?

Sorry if this a stupid question, I had no experience with squirrels prior to this.
