Hi. I am a soon to be chicken owner and I really want to allow then to free range during the day. I wonder how difficult it is to "train" a chicken to stay within a certain perimeter...in other words...keep them in our yard vs. wandering off into the neighbors yards. I work during the day so I was originally thinking of only letting them free range on the days I'm home so I can keep an eye on them for both this reason and potential predators. Any thoughts? Thank you.
