We have opened the lid on the hut so she can see daylight and know there is nothing in there unsafe. This morning she has finally stepped inside and I can hear her moving the bedding around so we are hopeful!
We have a large pond, 4 females 1 male Muscovy (and 2 Pekin males that do their own thing)
1 female made her nest in a floating duck house (12)
2 made a double nest in a roosting hut inside a pen and sit on their eggs together (28 of them)
And 1 made her nest in a bush across the street...
