I have my pheasant pen framed out and want to put a roof on tomorrow. The netting is a bit out of my reach right now, so I'm wanting to put a wire roof with a tarp over some or all. Is a chicken wire roof, covered by a sturdy tarp, secure enough? My sides are going to be hardware cloth, but I see a lot of recommendations to use HC for the bottom 3' of a pen/coop and then chicken wire above. About the only thing I'm worried about coming from above would be racoons? I don't even know if they can climb it, my HC is 1/4". SO....can I get away with chicken wire on the roof?
