This chicken run was by far the easiest item I have ever assembled. It is a great product for the price and will effectively keep chickens contained. It is not predator proof, but we plan to replace the chicken wire with hardware cloth and include a skirting which will provide extra safety from predators. Overall, we love this product and it does want it says it will do. The top and bottome door are an amazing addition and make it easy to toss treats in without the hassle of letting our girls escape.
