Thanks.
Will perform a covert OP tonight and insert the eggs under the sitting hen and cross our fingers.
One other question:
I saw her (The one that hatched the 5 ducklings) carry an egg out to the pond we made for them and crack it and eat it. I have never seen this before and it was quite a hike from here nest to the pond. I followed her when she did this hanging back a bit so as not to disturb her. She kept it in her mouth until she was in the pond then ate it. The egg looked unfertilized and did not smell when it was cracked. - SO....is this a typical trait or should I be worried about this behavior?
