I got home last night and found 2 hens and 2 pullets in the coop. Where were the other 11 hens and the missing pullet? They climbed up on top of my coop to roost for the night of course. Someone closed and latched the door so they couldn't get into the coop yesterday afternoon. So when I got home, I found them all up on top of the coop content, warm and happy. I was relieved but at the same time wondering how in the heck they got up there. Then I saw it. I had made them a ladder to help them get to the perches before I lowered them. They had always ignored the ladder, but last night had used it to get to the roof of my coop. Little boogers. Actually my rooster was on the ground. My "barbara" had parked her fuzzy patooty on top of the ladder and wasn't moving.
