How tall are Runner ducks?/Mini-ducks?

[mominoz]

I have an order with Holderread (sp)'s and realised I don't know how tall these guys are. I am also supposed to be getting 4 tufted buff geese from Metzger.I am thinking they will be about as tall as the geese--The reason I am wondering , is I plan to let the geese and Runners graze the house pasture (that will be dog fenced )in the daytime, and figure thay should be tall enough once grown that Hawks and such will leave them alone, especially with the geese around. WE do live in a farm valley with National forest sections adjacient.
I also have some mini-silver appleyards and 2 silky ducks ordered, how tall are they? like 6-8" cubed or something?

This is my first venture into duckies.....

My runners are not full adults yet but the ones I have seen I think were about 3 feet tall and really slender. Mine are easily 2 feet now

my runners come to about a little abve my knee. They are not as upright as show runners though....
