So I really like the look and affordability of both the Mallard and Rouen ducks but I'm not sure which type would be better to raise. I'm only looking to have them for entertainment (fun, ornamental purposes, whatever suits you better). They would be free ranging with my chickens if I did have them, that way they can get to all of the wonderful grass and bugs. Would a domesticated mallard (like they sell at Ideal Poultry) be too wild to free range? Will they fly off? Will they come to the coop at night? What about the Rouen, will they come to the coop at night? I know Rouen's are not good flyers so I don't have to worry about them going anywhere. I really like that the mallard is smaller. I'm not the biggest fan of fat (if you will) ducks. So, what do you think? Which one? Thank you.
