Yes turkeys will tuck their heads under their wing(s) to help them sleep better and it also keep them from losing their balance. I have walked into the woods early morning on a full moon ad it amazes me that you can see almost everything in the woods. Ive spotted turkeys in the roost and set up about 40 yards from them not spookign anything out of the roost. I try not to begin calling untill i hear the "red bird" sing. The cardinal is always the first bird to make noise, as soon as you hear him begin your calling, by that time the turkeys should be out of the roost and should have calmed down and forgotten about any noises they may have heard in their sleep. I have been very successful in the last 12 years of turkey hunting by following the simple rules that I go by. Ive tried calling before the cardinal would sign just for a research project adn found that the toms would head away from me, the next day I called right after the cardinals sang and the toms headed right to me.
