We went to Alaska a couple years ago and I know that half of the year there is only 3 hours of darkness and the other half is mostly darkness. I have a question the half where ther is only 3 hours of darkness. Usually chickens go inside to roost at nightime. Do your chickens only sleep 3 hours? Do you still put them in when it is like 8:00 p.m. even though it is still light out? Thanks for answers in advance. I am just really curious.
