Hello, my four pullets are about three months old and I'm confused by their nighttime behavior! They do go into their coop at dusk and I shut the door to the run. They all just sleep on the floor (not piled up - its too hot for that I guess) so I have been going out to see if they're still doing that, I have been waiting for them to get up on their roosts! They explore the roosts during the day, why won't they go sleep up there? The strange thing is, they are never just sitting and sleeping when I go check on them! I sneak up on their coop at various times (anytime about 10pm - up to 1am) and they are usually awake! Sometimes even walking around. Last night I heard a couple of them clucking at about 11:30pm. I thought chickens were supposed to get all chill at night and very still and sleep. Are my chickens having some sort of problem that is keeping them up, or is this just part of their normal night behavior? Thanks for any info!
