We had some that arrived 'from nowhere'; never did find out; which set up on the farm here. Agreeable to look at but we had to move them to the other end of the village because they took to making a very loud noise at first light, by the houses down the lane. They definitely need space; they're an odd sight in a farmyard, but they did have parkland next to it; and they can wander surprising distances for such a terrestrial species.Once they find somewhere to their liking, they don't go far, but they need a fair bit of space around them, at least 3 acres at a guess, there.
