When is the best time to roost turkeys in the evening or in the early morning?

Roost them at sunset, then come back in the morning and wait for them to fly down from their roosts.

the evening, then you wont spook em in the a.m. when you go set up on em , lolthat is what i try to do....usually i just try to setup where i know they'll be sooner or later and play the waiting game...

I am taking this as a rookie question. You roost (watch them fly up or locate them on the roost via a shock gobble) in the evening so you will know where to set up in the morning.

If you havn't done that the evening prior---you can use a locator call in the early morning to see if a turkey will shock gobble so that you can set up on it---or you can wait to see if they will gobble on their own.

Most of the hunters in SE MN and SW Wisconsin hunt private land as there isn't much that isn't private. It may be different where you live and hunt and there may be more or less gobbling activity in the evenings. Over the years, I've tried to get out there about an hour or so before dark and observe. I find a long valley where I can see and just setup and listen and watch. I've roosted a few by sight and a few by sound but there were many evenings where I didn't hear or see anything so be prepared for that. If nothing it passes the time before the next morning's hunt and time in the woods is always time well spent. In two seperate late season hunts, I managed to roost and kill two gobblers that flew right down to me so it can work after some soft clucks/purrs and then giving them the silent treatment. The majority of the birds I've taken though have been from 7:00am to 3:00pm.
