I've helped process chickens last year,but not Muscovy's, and now I'm getting ready to process my older 1 1/2 year old Muscovy Drakes, there's too much fighting going on between them. Does anyone know the right size processing cone to purchase for slaughtering....I've been looking on www.cconly.com at their stainless steel cones and its hard to decide between the KC-SS-M3 or KC-SS-L3 as far as the right size to stabilize them during the bleeding process ????? Also any experienced helpful Tips,Videos' anything to help me along with my first time processing would be very helpful ?????
