Apparently, if you leave the hatch to the coop open, something WILL get in, catch a chicken and drag it out of the coop...
Leaving ALOT of feathers behind as evidence.
To top it off, I was going to lock them in their pen today so they feel safe but I can't find one. I think she is hiding in the straw and I would hate to lock her out. Hopefully she will turn up before dark and I can close them in for a few days.
