After shipping eggs, it is best to let them settle before you start incubating them. The egg can be shaken a bit during transit and it gives the egg time to sort itself back out. It also gives the temperature time to stabilize. Unless the eggs had already been started incubating, letting them adjust to room temperature will not hurt them. Failing to do this should not doom you to a bad hatch rate. It just improves your odds a little. The main thing is that the eggs need to be dry when you give them to the hen. Cooler eggs can collect mositure (condensation) as they warm up, which can help bacteria enter the egg.
As the others said, if you collected them and did not shake them up during transport they should be fine.
Sounds like you have already given them to the hens. If you have, then definitely leave them. Disturbing them more will not help anything.
