I have a small flock of 2 chickens, a rooster (who at a previous home took on an eagle for his ladies and survived!) and 2 ducks. I have a decent sized fenced in back yard (pic. is from 2 years ago when lawn was put in). My flock does NOT have clipped wings. We are located in Alaska. Predators in our area are mainly the owls, hawks, and eagles. QUESTIONS: 1. If I let them free range in the fenced in yard, will they stick around or do you think they will go outside of the fence? 2. Will they make a mess of my yard? (mostly worried about the ducks) I don't want them destroying the yard, or God forbid get taken by a large bird... but I know they would enjoy free ranging and the shallow pool!
