Please don't think I am dumb...just a first time chicken owner. We have 3 sweet little chickens that we love very much. One of them is being very naughty and escaping from the back yard. She doesn't do it every night but when she does it is usually in the evenings around 7:00 or so, about the time they should be putting themselves to bed. Because we know her behavior we set an alarm to go out and check on them and up until last night on those evenings when she has jumped the fence we have been able to find her before she wanders too far. But last night we were in a situation where we were unable to get home in time to check on them until it was dark. She was gone, my son was upset and crying, we wandered the neighborhood until 11:00 p.m. with flashlights and couldn't find her. I got up this morning at 6:00 and went wandering again and finally found her. The little beast. What do we do? How do we break her of this habit? How can we keep her in the back yard? I don't want to lock her in a pen, I think it is mean, but I don't want her getting lost or killed either.
