I also learned that chances are at least one of my 4 ducks is a drake. We picked them all up till they quaked or squeaked tonight to get down and at least two solid quakers, so girls. We are unsure about the third, the one with the drake feather very much squeaked. I am ok with one drake and three hens! Do I need to rehome one of them if the other proves to be a drake with just 2 hens?
