We are first time duck owners, anxiously awaiting our ducklings from McMurray Hatchery this May. I've done a lot of research, and settled on an all female flock (11 ducks, different breeds). Has anyone else had a flock this large with no drake? Should we add a drake or 2? And if so, what breed would be the gentlest on the ladies once he's looking to mate? We are expecting 3 colors of runners, a blue swedish, pekin, buff, cayuga, silver appleyard, welsh harlequin, khaki campbell, and a white layer. Thanks for your insights!
