Found four sparrow eggs!

[TheOddOneOut]

They have already been touched and moved from the nest, and most likely the nest has been touched, too. If the OP puts them back the mother that laid them will not care for them.

Yup. But they should NOT have moved the eggs in the first place!
Now, likely four young lives will be lost.

I do think they shouldn't have been moved in the first place.

Unless they somehow clearly found the mother dead, and I'm not sure how they would even know, those eggs should not have been moved.

I’d try 99.5 and 50% humidity. Just feed them when they start begging and they need fed every 20 to 30 minutes! I was a wildlife rehabber for 20 years. Sparrows are funny little things once feathered.

Agree

It's actually illegal to take eggs or even disturb a nest in the United States.

Yup.
I am very against people thinking that the birds/eggs are better off with them, a human who doesn’t know how to incubate them, feed them, and teach them, and they then take the eggs. It’s not rational or kind. They aren’t better off.
OP, I truly don’t mean to be rude. I’m not mad with you, and if the situation is different than I thought, and the mother is dead, I will do my best to help.
But if you have no evidence the mother is dead and have a way to put the eggs back, PLEASE do.

Putting them back in the nest is a even more sure death sentence. Snakes, other birds, racoons, and multiple other things will eat the eggs. The mother will not return and hatch the eggs, or if she does return she will kick the eggs out of the nest. Though incubating them just makes 4 babies that are very needy and difficult to care for.

It's too late in the year for any wild birds to be laying, I doubt they're any good.

There's nothing saying the mother would abandon the eggs. That whole they smell humans and leave is wrong, and more than likely just so kids didn't touch baby birds
