Hi, I'm a newer Duck mama. I have two pekins and two khaki cambels that are 4 0r 5 months old now. Ive been working on their enclosure , housing, run and pond this summer and plan to complete an aqua ponics systeme for them next spring. I don't plan on running the pond this winter so I decided to wait till next spring to finalize the aquaponics set up. They are so cute but so much more messier then my chickens! their run is a mud pit ! I have rocks around their pond and we started with turf in the run but that is long gone. should we use straw on them play in the mud ?
