The Case of the Missing Buff Orpington

The first mystery is why the Buff Orpingtons are the ones that go missing.  Why can't it be one of the Americaunas?  I don't like them nearly as much. 

And then, where is the hen?  There are no piles of feathers or sad little carcases anywhere in the yard to give any clues - I am just down a hen.  We don't have fox or any wild predators.  Sometimes there are owls, but they are only about half the size of these huge hens. 

Even my dogs would leave a few feathers - they aren't smart enough to eat the whole thing to hide the evidence.  I doubt Nani, the cat, could do the deed, although I see her checking the hens that invade her area under the greenhouse tables with an evil eye.  Nani is a rather small cat and has never made even the half-hearted attempt to stalk, much less pounce, on a hen. 

This is the second Buff Orpington that has gone missing.  The first one, I thought maybe she was brooding somewhere (they do go broody) - even though it would be in vain since the rooster had his fatal accident after attacking the nervous Gibby Crazy Horse.  She never came out of the woods, though, so I guess that wasn't it. 

These hens are already over a year and a half old and I was already thinking about getting a new batch, but I still resent that it was one of my beloved Buffs that are gone and not the less productive and less affectionate Americaunas.
