I hate to be a big downer, but problems can arise with drakes who are raised in close relation to chickens. "Duckens" or "Chucklings" were on his mind & he almost killed my SLW one day. He'd never gotten as much as 2" off the ground, but one day he found the where-with-all to fly over his fence, down the hill & land right on top of the poor thing.
(He was fenced off because of a series of other disturbing attacks on my girls.) Unfortunately, my guy was just too comfortable with the chickens. I now have a "Girls Only" rule on my property - but then, I am trying to keep my "operation" small.
I know not every drake behaves as badly as mine did, but it is something to bear in mind when planning to raise them as one big, happy flock.
