Hi Bonzo,
They only have three legs, this ensures they cannot fly, one leg is shorter than the rest so they can walk on hillsides. To catch these rare elusive creatures, one must go out at midnight, full moon preferably, trousers rolled up and wellies on to keep the noise level down.
Then you must very softly whistle the tune, "Oh whistle and I will come tae you my lad" and if they like the cut of your jib, they will respond by running towards you, a quick clout over its head, and the deed is done.
With regards to inducting them into Norfolk, they only breed on mountains and hillsides in Gods Country, or occasionally Wetherspoons! So regretably your idea cannot be put into practice, as they would have great difficulty walking on the flat Norfolk earth!
Do enjoy your trip to Wetherspoons, I suspect we may do something similar, if only to give SWMBO a night off from the kitchen patrol!
