A few years ago my husband built me a couple of coops with only 3 sides because we live in Florida and the summer heat. I had my Rhode island Whites in one of the coops. I started loosing birds (killed). I couldn't find any way something was getting in. I have electric wire around the perimeter of all of the coops and pens. After a couple of mornings of finding dead birds and my survivors bloody I moved them to another pen. I put a game camera up. It was an owl killing the birds. I had 3 birds left, a male and 2 females. I need to mention before I put the birds in that pen they were in another pen that a coyote went in over the fence and killed several. I shot at the coyote and didn't see it for a long time (the first 2 pictures) but that pen had no electric around it. I built my RIW flock back up with those 3 birds. I did collect the eggs and put them in my incubator. Good luck...
These were the birds that the coyote attacked. The survivors were put into the open coop and pen. This one I usually use for a quarantine coop and pen.
After the coyote and the owl attack these were what was left. I put the survivors back into the quarantine coop and pen.
I have heard horror stories about predators killing people's chickens. I think I would be devastated. Thank you for sharing your story. It's sharing like this that helps me to learn what to do, what not to do & what precautions can be taken. So far, we have been fortunate. The only thing I have had to deal with is our daughter's cat stalking the chickens & her dogs chasing them (the chickens in their pen & the dogs outside of it). We have 5 little, bully bantam roosters that help teach the younger birds how to keep an eye out for flying predators. I am grateful for that since we do have hawks that fly over & check to see what they can get into. My dog keeps the cat at a distance from the other birds. The cat doesn't bother the bantams. They are too feisty for her, I think. I know we may have to deal with loss of some of our birds sooner or later & I dread that day. Your story gives me hope too. Hope that we can actually build our flock with 2 pullets & our rooster & his spare.
