We have 5 PET (hand raised) ducks and that live in a ~1000 sq ft preditor proof enclosure. At this point we have 3 drakes and 2 hens, not the best ratio. I am thinking about adding 2-3 girls to the our tiny flock of pet duckies. Any thoughts? 1 Pekin drake, 1 Cayuga drake, 1 Welsh Harlequin drake, 1 Pekin hen, and 1 Cayuga hen.
