I've been told the regs are that way so the hens have peace and quiet to sit on their nest. When they fly down from their roost they usually feed for a few hours and around 11 or so go to their nest and lay their egg. Don't know if this is true or not but my grandfather told me they only lay one or two eggs a day until they have a dozen or more. They leave the nest for the roost each night until they have a full nest to hatch. That is when they start sitting on them constantly for them to hatch with a short break now and then for a quick meal and drink. While they are still laying their clutch of eggs is when the *****, skunks, possums and yotes invade their nests. They can have as many as three clutches of eggs by the initial fertilization until they are successful with a hatch. That is when they have to deal with the hawks, owls, bobcats, ferrel cats and yotes. It is a wonder that any at all ever survive all of the predators that are out to get them. AND THEN......us humans start chasing them down with out shotguns. Oh.....the life of a turkey..... not the greatest.
