I've been reading other posts about Guineas here and as usual I learn a lot. But some folks say, they should roost in the trees and some say the coop. Mine will not do either. They sleep at night under my living room window. Should I be training them to sleep in the coop or the trees? I figured it was automatic since the coop was their home for about 6 weeks. They go in and out of it all the time but will not stay in it at night. I can't believe it's safe to always sleep on the ground out in the open. What should I do???
