Thanks for the replies.

Yes, we have something separating the crate from the water. I agree, too, that we should use some vermiculite on the next one. We didn't add water to the tub until it was already in the 'bator. We're down to 3 eggs with good veins. 2 of those 3 look great, and the 3rd is questionable. Hope we get at least the 2 babies.
