No, I didn't, and I will, but it doesn't matter. You admit to closing at 10pm after dark and didn't do a head count then.
The attack happened with an open coop, so you know how it got in.
I'm still inclined towards raccoon first, then fox. Bear would have made a bigger mess.

Yes. Predator of some sort. Raccoons will often kill in site and then return later.
Somehow I doubt bear. That would have knocked over stuff and likely scarfed some chicken feed or at least nosed it. They tend to make a mess when they nose through.
And a fox could have also done it...
