crop squares, not circles

With each pen move the poultry: turkey, egg layer, or broiler leave perfect squares behind. Or sometimes a rectangle.

The National Guard trains helicopter pilots to fly out of an airport less than 10 miles from here. There are constantly helicopters flying over the farm, in all sorts of weather conditions. As hot summer days stretch on and every pen is in use the ground is an ever changing mosaic of color changes, patches of high grass, low grass and bare soil. It looks cool to my eyes here on the ground, it must look quite interesting to the folks in the helicopters.

Or if they are really just learning to pilot maybe scenery watching is not on the to do list.
