I came across an interesting product at Home Depot that I thought I'd ask about before I bought any... It's a plastic chicken wire: http://www.homedepot.com/Outdoors-Fencing-Wire/h_d1/N-5yc1vZ1xipZbb00/R-100384028/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053 I was originally planning on buying the vinyl coated chicken wire for my coop, but this to be an interesting option as well. Now, I do have cats and dogs that will be around this coop from time to time, my main concern is would it withstand a determined wandering tom cat or some random city critters (we've had a couple opossums but my dogs killed them) ? Oh, and this coop is within a 6' wood privacy fenced yard. So, has anyone used this or something like it?
