I have 3 hens and one rooster that I keep in a small coop that's inside of a sturdy 10x10x6 dog kennel with a tarp roof (there's an electric fence outside of that). When home I let everyone run around in the kennel but if I'm gone and at night everyone is locked up in the coop just in case anything gets in the kennel (hopefully I'll get that secured soon with hardware cloth). They have always been perfect about going up in the coop at night - nobody seemed to want to be out after dark. Recently we put up tarps around 70% of the kennel to cut down on the amount of weather that could get inside. Now this has happened - last night, well after dark, our rooster was perched on top of the coop and not moving. The hens were tucked away in their roost but he just sat there like he had no intention of going up for the night. The theory I came up with was that maybe now he's starting to think of the kennel as his coop instead of the kennel as his run. Does anyone else have any thoughts? PS: I took him off the coop and shooed him inside. He needs to do his duty and help keep the hens warm!
