As we were finishing our coop my DH called me over and with a grin explained he had installed the wrong type of latch. He would get another one and replace it asap. Well, as I entered the run this evening and pulled the door shut I heard an click that confirmed I was locked in the coop/run. Tried to "macIver" my way out with my glasses, but without a pen, paperclip or chewing gum it was hopeless. Over an hour later I was rescued by a friend that stopped by. I saw the same grin on DH's face when he got home and heard the news.
