I am thinking I need to rake--right? I mean there are lots of leaves in here. Should I be concerned about disease? I mean this pen has not been used in over 4 years. the mesh wire is tight enough to keep predators out--except maybe snakes. All input is appreciated because I have NO idea what I am doing but I will learn as I go and read as I go. My hope is to get 3 hens and 1 rooster..perhaps about 3-4 months old. Is that too old to teach anything? Must they stay in the pen all the time?? again--never ever done this but am soooo excited.. thanks ya'll Angie
