We have backyard chickens in the city. Our chickens free range during the day & go in the coop at night. We hadn't been locking them in the coop at night because we honestly just got too comfortable & hadn't lost any until recently. We have lost 4 of our 8 chickens in the past 2 weeks. We are assuming it's a raccoon since we are finding the birds split open but not eaten. We are clearly trying to lock them in the coop at night now & set a trap to catch the raccoons but now the chickens refuse to go in the coop. They sleep on our back porch as far away from the coop as they can get. What can we do?!
