My ducks forage a good bit of the day.
So do my chickens.
When not molting, my ducks lay pretty darn often and they are 4 and 6 years old.
When not molting or sitting on eggs, my chickens lay pretty darn often and they are 6 months and 3 years old. Though somebody has been slacking or is laying them somewhere else, I'm leaning toward the latter.
My ducks enjoy their pond and pool of water.
The chickens just drink from it.
My ducks cost more because their little pool gets cleaned and hosed out often, thought their big pond does not - that is every year or so for 1000 gallons.
I use duck eggs for baking and gelato.
I'm not a fan of yolks in an egg to be eaten to begin with, so I don't like duck eggs for my breakfast eggs and eat the chicken eggs for that.
If I could only keep either chickens or ducks, I'm not sure which way I'd go.
