Show a picture of your setup. A Great-horned Owl should not be able to pack off an adult standard-sized Orphington.Hello, I have a hobby farm in southeastern Arizona. Have 30 or so laying hens and have had a horrid year with predators of the flying variety. Hawks and Great Owls as far as I can tell. Spent many hours totally covering my large hen yard with bird netting , sides go up ten feet and across the top of the about 60 x 60 foot yard. What a pain. Last night for the second time some large bird predator got in and took off with an adult buff orpington laying hen and I am just sick. I get the idea that I need electric netting and that means the yard will get much smaller (it is just dirt- not like there are good things to eat etc). But I will have to also cover the top somehow...any ideas or will regular heavy weight bird netting work across the top?
