Just the other day we noticed that one of our three hens was missing. We live in an urban neighbor and have an eight foot privacy fence as well as a coop. Our hens free range during the day. We searched the whole yard and couldn't even find signs of feathers. None of our neighbors had seen her (in case she had managed to escape) but one of them said that they did see a very large owl near our house earlier in the day. Has anyone heard of an owl being able to snatch up a full size Ameracauna hen without a trace? It happened once they were out of the coop because I saw all three of them that morning...
