One of the joys (?) of free range chickens is that they don't always elect to do what you want. I would prefer that they sleep in their coop. My neighbor went through a lot of trouble driving blind down the road with the coop on the front of his Bobcat so that our winter flock could have a nice warm place to sleep during the winter. This white chicken has no respect for his sacrifice. She insists on sleeping on our front porch, using the back of a rocking chair as a sleeping perch. Do you think she rocks herself to sleep?
The bummer about a chicken taking up residence on the porch for the night is that 50% of a chicken's poo is pooed while they sleep. So a chicken sleeping right by my front door is going to leave a massive pile of welcome for any guests. Instead of trying to coerce the chicken into sleeping in the coop, which I've tried, we decided not to fight with Mother Nature. The hubs put a bucket under her perch to collect her droppings and then, in the morning, empties the bucket into the compost pile. We've become her personal chamber maids.
