kortwiekenBirds can fly. Poultry too. To avoid them to fly (away) you can once a year, after moulting in the autumn trim one wing. After moulting, there is no more blood flow in the wings and the long (flight) feathers (remige, pinion) can be smoothly cut, just like fingernails. The surgery is done on one wing. (With two short wings can still flap, with one long and one short, there is no flight control anymore.)


Easily and permanently is to the day-old chicks (before they are 5 days) pinioing: only the last wing member, while maintaining the "thumb” with three pins, is amputated. Handy is a glowing wire (the principle of a soldering iron). There is no blood involved.
