I had two guniea fowl when I left for work. When I got home 1 is missing and feathers are everywhere. And the other I found intact but dead. They were in our chicken yard that was fenced but the gate was open as our chickens free range during the day. I have 7 chickens and they were all fine but they were hiding under a Leland cypress tree and would not come back in the fenced area until I went in. The one fowl was in the corner of the fenced area, but no obvious wounds. Then I found 3 piles of feathers I presume from the other hen, but no hen found. Anyone have any ideas? My husband thinks a bird of prey, I think a dog since the other bird was killed but not taken. These fowl were not afraid if our dogs so I'm thinking a dog... But our chickens are fine....?????
