Hi,
I can do a chicken in less than two minutes. The last time I broke down a duck was too long to even recall, though they cannot be too different from a chicken.
If you never did it before, sure it takes longer. I almost never buy chicken parts, unless it is cheaper than whole chicken. I buy chicken at Costco for 89 cents per pound, then cut it up according to my needs. Learning to break down a bird can save you a lot of money.
I visited the Navy's Culinary School at Great Lakes before they moved. I watched a newbie very carefully peel a cucumber. It was such a slow process, it likely took far longer than what you and I would do.
Regards,
