Excellent list and great reading! The only thing I'd add to this, from personal experience, is to watch what your hens are actually eating if you use mixed grains or mix your own feed. If your hens are leaving a particular grain or other bit in the feeder until the last bit and only eating it when super hungry you may want to switch that out for something they will eat. Feed left in the bottom of the feeder will attract insects and pests and ruin all your good work at being frugal.
