A few years ago we upgraded our chicken coop with a nice big one the Amish built for us. We decked the coop out with nest boxes, perches, and feeders. Unfortunately, after we got most of the chickens trained to live in the coop, a raccoon got in and killed half of the birds one night. The survivors of that night of flying feathers have been too traumatized to spend another night in there since.

I have always been suprised at how well the birds deal with Michigan winters. The peacocks have never liked being inside. Even when they were penned up, they would rather roost outside in their flight pen than inside a coop. Now that they are free to roam at will, they forego the opportunity to sleep in the dry coop and perch high in the barren willow or on the railing of the 2nd floor deck. We have never lost a bird to weather exposure.

Finally we do have a chicken and a rooster who have found their way back to coop life...
