I've got 3 Dominique hens that sleep in our apple tree instead of their coop. They haven't been laying in there either. Last night I picked them out of the tree and locked them into the coop with the other 6 chickens. My idea is to rehabitualize them with the nesting boxes and sleeping in the coop. Am I on the right track? If so how long should I keep everyone inside? I was thinking 1-2 weeks. They are free range chickens.
