So sorry for you loss. I invested in some game cameras. I put them up in different places and was amazed at the predators that roam here during the nighttime. I have had birds killed in the past around dusk and dawn by owls, during the day coyote, hawk and fox, night fox, coyote, bobcat, possum and owl. I have trapped and eliminated predators that have killed my birds except birds of prey which are legally protected. My coops and pens are pretty secure. I have electric wires around my coops and pens which keeps out most predators. I have concrete under the gates due to a fox and heavy duty netting covering the pens because of mostly aerial predators but years ago I did have a coyote go over a 5' fence into a pen and back out with some birds that also went over the fence to try to get away from the coyote. I did get a shot at the coyote but I had bird shot in my gun so even though I'm sure I hit it, I didn't kill it. My favorite bird was killed during the day while dust bathing. I was out painting on the coops. It just sneaked in and got her. I caught the fox and eliminated it too. I don't bury the birds outside of the pens because coyotes would dig up the bodies, so now I bury any dead birds in their pens. Good luck...
Last night.
