How tall are large breed ducks?

[EEmomma43]

I’m converting a shed to a coop for a mixed flock. Currently I just have chickens and will be moving them into the shed and getting ducklings in the spring. Can anyone tell me how tall large breed ducks like Saxony, Silver Appleyard, and Buffs are so I can plan how high to mount the chickens’ poop board and still give the ducks good clearance to walk under it?

I have some of those breeds and inside my duck house I have some plastic tables which are actually sections from a big shelving unit some of the ducks jump up and sleep on top and some of them sleep under the clearance is 18 inches and they’re very happy with it, but don’t forget Ducks are very good at ducking.
Yes pun intended.
It doesn’t have to be so high that they’re standing completely upright underneath it. As long as they have other space to walk around without a shelf above them. I like to give my ducks at least 4 ft.² each floor space inside of their overnight coop.
Something funny I’m sitting outside with my Ducks now and the light breeds (my Indian runners) when they stand up right they’re taller than the big heavy Ducks lol they stand like a little bowling pins
