I KNOW we have a resident coon. We see him/her at night occasionally and it can sometimes be spotted sleeping in a tree in the woods behind our house. I don't have concerns about my chickens' security at night, but I do let them freerange during the day between the hours of 9 and 5, or thereabouts. Having read that dawn and dusk are prime predation hours, I don't have them out then. I am usually home and our smallish yard does have a lot of human activity most days (kids and I are out there a LOT), not that that probably matters much. Should I be concerned about the coon taking a bird during the day?
