So sorry for your loss. I agree with the other posts. I have covered large pens for my birds. My pens are covered with good heavy duty netting. I also have electric wires around my coops and pens, and nothing has gotten past the hot wires. I had a fox dig under a gate and kill some birds so now I have concrete under the gates. When I first put up the netting I ran short and bought some online that turned out to be crappy and an owl went through it three times. Each time I replaced it with more crappy netting because at the time that is all I had. Since I have replaced it with some good heavy duty netting, problem solved. My DH and a friend built me some coops that were open on one side but we live in Florida. Their hearts were in the right place but not a good idea to have one side completely open. I put tarps over them. Here is the owl going through the netting.
