I know they are messy as ducklings, but are they messy as adults? I have 4 chickens and I clean my chicken coop out every 2 weeks, but if I have to, I will do it once a week when I get the ducks. Are they messier than chickens? As in messier than pooping in the nesting boxes, on top of the boxes, and on the porch? I already know that the kiddie pool I was going to get them will be dumped and refilled daily.
