Is it likely that a smallish EE could be taken by a raptor and there be nothing, not even feathers, left? The chickens were in the yard yesterday, and the humans were all inside (the dog was in and out, but she leaves the chickens alone, mostly--she does occasionally rush them to see them react, but she stops 2-3 yards away with a goofy boxer grin. She's more interested in what we toss them as treats, even going as far as eating BOSS...) Anyway, I went out around 5, and everyone but Cookie were already on the roosts. My daughters and I scoured the yard multiple times--we've only got 0.18 acre, so it's not like it takes that long to look under and in the sheds, and under and in the trees, or under everything else that a chicken could conceivably get under. Later, I remembered that I'd heard an alarm call, but I'd thought at the time that the dog had rushed them (or that someone was finally laying--we'd only gotten 1 egg yesterday, from Cookie--she and Frieda being the only 2 whose eggs I can identify for certain.) I suppose it's possible that Penny did rush Cookie, and Cookie ended up over the fence, and that one of the neighborhood dogs got her...
