Ok, thanks. I think we have it secured now. My hubby built the second door so now it is a closeable coop inside a covered run. Hopefully, that takes care of the problem.I would agree with those that say racoon... if there is any opening they can squeeze through they will. Of course if it was a racoon, you are probably lucky you only lost two birds... and the rooster would not be able to fight off a racoon... even a small one.
