My drakes were always the Sweetest too. I think they don't have to have the instinct in them to protect their young like the hens do so they are just more friendly. That is with the exception of this latest one I got that turned out to be a Dusky Mallard Runner Drake. He doesn't come near me to amount to anything and it a lot more on the wild side for some reason. I still wonder if he was not half wild and just a fluke in the bin at the store I got him from, Rural Queen as you call it. He is beautiful though so I have let him stay for now until I see how he behaves in the spring. Good luck with all of yours Frank. It's hard to let them go, how well I know.I will curse about them in Spring! - And maybe buy some Pekin Hens to to show them some boundaries.
Or some Muscovies...
Or i build a drake-jail…
I really don't know, those drakes are the sweetest ducks i have ever had, they come running to me and still cuddle with my feet.
