I think they go into a deep, coma-like sleep, once they’re good and asleep. That’s why it seems they don’t see good at night. I suspect they do see pretty well at night, with there being variance between breeds as how well they see in low light. But they’re in an altered state of mind regardless. Unless they get woke up good, then they go into fight or flight mode. Wild turkeys seem to be the same. When turkeys are out, they’re out. But if they wake up, they’re aware of almost everything happening around them. If I peg a gobbler on the roost I want to kill the next morning at daylight, I get under his roost about 2 hours or more before daylight and wait for him to wake up and fly down next to me. If I try to get under him just before daylight, he’ll already be awake and aware of me.
