Steve..........it is sad you lost your birds. But given the circumstancesI wouldn't know who else to blame. If it was your responsibility to lock um up, then it falls on you. These post saying it's not your fault just flabergast me. But the one post that said beat yourself up for 2 days then get over it and go on is pretty spot on. We all do make mistakes but it seems like each time we do our hens lose their lives. I left my coop access door open one night. When I saw that the next morning I got a cold sweat. I could have killed all my chickens. And make no mistake it would have been on me. Nobody else handle the chickens but me.
Now we learn from what we did and move on. Believe me I double check the coop, nest and the door before I walk away. These chickens are getting me attached to um. I have to look after them, them look to me to protect them. Good luck with the new hens. You gotta get some more.
That news is sad.
