Hey Cuckoo!
You'll love them!
When we first got ours, we clipped but now the feathers are growing back we won't do it again as they know where home is. We used to lock them up every night but now they can flap they roost on the goat house roof. I don't worry about the fox with them, by the time foxy has got up there they will have flown away or knowing my drake wreaked evil vengeance on it!
They make fab ratters and mine all got really tame. Mine don't like being picked up and my arms bear the scars to prove it, but will come to a call and wag their tails and bob their heads in greeting, then follow you round for the day. I don't trust them with the other drake yet as it's spring, but Daffyd the rat killer also used to 'defend' me from my bastard cockerel when he was still here. I found bribery with goat coarse mix makes them adore you forever!
So far this year we have had 2 clutches of 9 eggs from them, and the next time they lay I will let them sit. They stuff themselves full of slugs and snails so make themselves useful even if you don't eat them. I'm sure any surplus birds should you wish to breed would sell quickly as table birds or could be swapped for something your OH can eat.
HTH, you will probably guess that I LOVE my muskies to bits
EDITED TO ADD;
MAK, It's me that has the rat killer! but he will eat from my hand and follow me around like a puppy dog, he likes a scritch but WILL NOT tolerate being picked up. They are often just specks at the top of my neighbours field, but come flying/flapping back as soon as I call them in
