I'm trying to get more folks interested in them here locally since they are now legal in town. I actually had about eight silkies before they were legal. Grin. I loved them! Something got every one of them one night. No bodies were found. Just a few feathers. Kinda scary.
Oh gosh that's awful!
No evidence is something big enough to carry the whole thing away. Coyotes, foxes, etc. Usually I think racoons are bad about killing and just eating the crop out of the bird, and leaving the carcass. Hawks can also fly away with smaller chicks. Dogs will take them away too. I had one golden comet disappear, we think a hawk got it.
