Thanks for all the feedback. Just a few things. They are secured in a coop at night that is locked. No sign of entry. The coop itself is enclosed in a 40 x 40 area. I think it is happening at dudk or dawn. I made sure to put all 4 remaining bird in last night and they were safe and sound this morning.

Several years ago I had an issue with a bobcat. It killed 14 birds. I set traps. It didn't come back the next night but did the following night and I caught it.
