Question about Broody Hen

[Jujubeans2008]

Hello!
We currently have a Maran sitting on three eggs.
There have been times where we have come home and noticed that the hen has switched nests but did not take her eggs with her. This has happened twice, and we aren't sure how long she was off of them. Is it possible that these eggs are still viable? How long can momma be off of the eggs? This is our first time with a broody hen so this is all very new to us.
Thanks!

She can be off them for an hour I think.

A hen wont move her eggs to a new place if she moves

We just candled the eggs and we saw one of the embryo's in one of the eggs moving, so it appears that it is still alive. One's shell is too thick to see anything and the other one was super porous and hadn't developed any. Fingers crossed they will still hatch.
