I'm planning a peafowl pen/aviary. 100 square feet per bird, shelter from north wind and elements. Sides will be 6 to 7 feet high, 1/2 by 1, 14 gauge hardware cloth for first three feet, then 2 by 4 fencing the rest of the way to the top. Flight area will be 12 to 14 feet high. Predator proofing is big concern, so I'll probably use electric wire around base and near top. I've read varying opinions on flight netting, knotted poly vs chicken wire. Raccoons are a problem here! Advice/comments/suggestions? Dr T.
