We made a pen that's 24 feet on all four sides and its sux foot tall with chicken wire over the top. We have 12 babies and a rooster and also to Peking duck baby's. We will be picking up between 6 and 12 9 month layers is this area big enough for them. We also have a 4 foot x 8 foot coop and also a 10foot x4foot coop. Will this be big enough for the amount we have and be getting?
