I think I will sleep less once it gets cooler. I get tired every morning after making my rounds. I usually go out by 9 and by noon I'm beat. I have lunch and sleep a couple to 3 hours and then work most of the rest of the day at something not really tiring. I have a good balanced diet so that's not the problem. Days I don't have any heavy lifting I use fewer pain meds but that doesn't seem to change a thing. Wells it's time to go out and close up coops for the night.
