My chickens are night owls. AND early birds. Whenever I have a need to go out back, regardless of the time, my favorite chickens run down the ramp to talk to me. I mean as late as 1am. Don't they need sleep? They sure are up before 7am. I tell them to get upstairs to bed and they do go, but isn't it weird that they are not sleeping deeply? They seem fine all day, not underrested or anything. I'm not really worried, just curious if it is normal.
