do 4 ducks and a newly seeded grass run make a good mix?

[Silkie-Feet]

yes they will be in it 24/7, but only in the spring,summer and fall months. BTW, can a cayuga and mallard breed?

Yes, they can breed and produce fertile offspring. All domestic ducks apart from Muscovys are descended from wild mallards and are essentially the same species, just with different colours and sizes.
