Hello all, I have Rouens and i'm wondering if i can let them out of their 15 x 6 x 5' covered/fenced enclosure during the day. They're still young at 13 weeks, so I'm going to wait (due to the plethora of chicken hawks in our area). My chickens/rooster always went back to their coop at sunset. Do ducks do the same thing or will I have to herd them. (They'll be free to roam in a large fenced backyard during the day.) Thanks!!!!!!!
