Hi. My ducks, some of them anyways, live with my chickens. So yesterday for the first time ever, I let my chickens (and therefore ducks) out to freerange. When it got dark, all the chickens headed right back in, but the ducks lingered. My ducks dont sleep in any of the coops, they prefer to be outside. In fact, I dont know if my ducks ever sleep as they seem to be up and quacking all night, lol. Hhow do you all get your free ranged ducks to go back into the run after free ranging at night?
