Jwcreen, I'm afraid I don't have an answer for you, but I have a question of my own. I have a mallard nesting on my rooftop. We can see Mom and the 6 eggs from a bedroom window. How the heck are the kids going to get down and to the nearby lake? I read it takes 2+ months for them to learn to fly. Should I be moving this nest? Perhaps someone can answer our questions.

If you can close the hen in with the nest in the new location for a few days she might come back to it to finish laying. If not, I'd keep moving the fresh eggs to the new nest and close her in when she's ready to set.

The ducklings on the roof are going to jump off, bounce, pick themselves up, shake themselves off and follow their mother. If you happen to see them when they're ready to go you can try getting them down. The hen might have a fit and attack you, or she might wait for you to set the ducklings down and waddle off with them. Is this a wild hen or one of yours?

Young tree ducks, Wood ducks drop many feet to the ground before heading to the water. They have such light weight bodies there is no harm done; baby mallards are quite light also so as stated, they will probably be OK.
