Came home from work today and looked towards my pens and saw a silver in a pen he wasn't supposed to be in. Walked down and realized him and his hen were not in a pen at all but walking on the outside of the pens and their door was wide open. I believe my 7 year old left their door open. It had to be open for about four hours. Well I walked towards them and corralled them towards their pen and they walked right in, no problems. Thank God they stuck around and were easy to get back in.
