Rouen, mallard or something else?

[Heatherwicz]

We recently just picked up two ducklings, the only thing is they are unknown breed. We tried searching only but we couldn’t exactly figure it out ourselves, is it possible the ducklings might not even be Rouen or mallard?

I believe those are ADORABLES
Very common duck, found in many colors!
They look like our Rouens, but the bills are very dark

rouen (2 stripes full length of face, one through eye, one under.)
mallard is 1 stripe over eye
wood duck typically is 1 stripe over eye maybe 1 under but they don't go far past eye and connect with back of head coloring
