I have a pen with peacocks and pheasants in it. I have now lost 1 red golden, and 4 lady amherst to an owl. I know it's an owl because he is very bold and has tried to take, and has gotten birds right in front of me. I put a cover on it and he hits from the side, I moved the perches, but am still losing birds. Is there anything that will scare him away, oh and he isn't scared of lights either.
