Found Bluejay nest, knocked to the ground with eggs/hatchlings..

I am guessing another bird attacked the nest. The other 3 eggs had the babies still half in them and a hole pecked to the head. I found one still barely alive and quickly scooped it up to warm in my hand. It is still breathing as of 1/2 hour later. What do I do now?
Here is a pic:


Does it have a chance for survival or am I just prolonging the inevitable?
What do I feed it? How do I feed it? I guess they were close to hatching since this one looks to be well formed. What do you think?
Thanks for the help.

Put them back in the nest, put the nest back in the tree. That's their only hope at this stage.

I doubt seriously if it will survive.

If mama's still around she'll probably build another nest and try again.

It passed.
Thank you for the advice anyway.

Rats I saw this too late! I rehabed 3 of them a few years back.
