And that's where your thinking went a bit off track: Wild Mallards do not just lay an egg a day or so. They carefully select a nesting location, then lay a clutch of eggs and start sitting.
Momma Mallard will defend her nest with her life, going on the attack against predators twice her size, pretending to be injured to draw the attention away from her eggs, doing everything in her power to make sure that her eggs and later her ducklings will survive. That includes walking her offspring to a certain HillBilly who is dumb enough to make weird noises when he spots the little ones and hands out large quantities of free food.

There is nothing wrong with going for the best available equipment if you can afford it and it is important enough for you.
