I have the dumbest chickens and ducks out there. i free range, and a 12x14 shed converted into a coop. i tried the 5 day lock down, that seemed to introduce them to it, but they still choose to stay outside, they dig under everythong to get out of the cold and wind, but forget about going into the shed. i have food and water raised up off the ground just inside to shed door to invite them in. they will go into eat, but come nighttime most will roost outside in the rain the wind. what am i doing wrong? how will they survive the winter and snow of new jersey? 19 chickens 2 ducks 2 turkeys i nervous keeper, that's me!
