protecting new ducklings

We are on a learning experience! Our Pekin Duck has been sitting for about 5 1/2 weeks and an egg has hatched! We found the duckling outside the pen. 😳. I took it and put it in a brooding box. It is lonely! Has anyone taken their babies at night to keep them safe and return them to the nest...

I have 6 brooding Muscovy. One clutch has already hatched. The mom had those tiny babies out foraging all over including the pond. One of our girls that hatched 2 ducklings about 4 weeks ago disappeared leaving her babies unsure of what to do. We miss our Sweetie Pie:hit I put those two babies...
