I converted a 12x12 chain link dog pen in to a coop for my silkies (it has fencing covering it as well), and last night woke up to a very upset rooster and ran outside to find the possum with the entire hind end of the rooster (only the feathers) in its mouth. After I startled it and we stared at each other for 5 minutes or so, it went right through the chain link! I didn't realize they could fit through those holes. How would I go about reinforcing it? One of my hens just hatched our first ever chicks last night as well, so I am worried about them. I didn't think to take my gun with me or I would have shot it last night. A month ago one of my English game bantams disappeared and we found her sitting on a clutch of eggs near the coop under a fallen tree, and something ended up getting her and eating most of the eggs as well, so I am guessing this might be a return visit. HELP!
