Muscovy Nests and Feed Questions

[wilded]

I recently acquired 8 hens and 2 drakes all a little over one year old . I clipped some wing feathers and am keeping them cooped until they get used to the place. They are laying eggs on the ground and not in the chicken nest boxes. What is the best nest box for Muscovy ducks and what is the best feed for them while cooped? Thanks, ET
