My husband is going to build a run for our chickens and it's going to be 16 ft long x 8 ft wide x 6 ft high. We're going to use 1/2 inch hardware cloth along the run. We're also going to have the hardware cloth coming out 2 feet on the sides (Like an L shape) and cover that over with dirt so that if a predator attempts to dig, it will run into the hardware cloth and hopefully give up and not think of moving back a couple of feet. My husband wants to make the roof out of plywood since we are on a very tight budget right now. We're only doing this because we recently lost one of our hens and a couple of her chicks to what we suspect was a fox or coyote. Until recently our more experienced hens were free ranged and our dogs are usually outside with them during the day. They are not LGD's but they're pretty territorial and we've never had an issue until now. At least one of our dogs was outside when it happened, so whatever it was had to be sneaky... Is the plywood roof a good or a bad idea? We are just trying to save money (that we don't have to begin with) while also trying to make it more weatherproof as we are in NY and get our share of rain and snow. Thanks in advance for your input!
