Special requirements for Call ducks?

[BkYrdDx]

I'm hoping to buy a Call drake or maybe an East Indie to show competitively. I currently have a small flock of two Welsh Harlequin ducks and a Cayuga duck for egg laying purposes. Would they likely get along with a Call, or could he get hurt? Are predators a concern for a free range Call? Could he fly out of my yard?

POssibly, i don't run my calls with my larger ducks, that would be something you'd have to watch for, generally bantams can be picked on by larger birds, so one does have to use caution, personality of the birds will play a key role, plus remember drakes will compete regardless of their size.

I don't free range my calls, they are pred prone, they are very good flyers, so that should be considered, i leave mine full flight but their all penned.
