Tailfeathers, Why are you feeding them so many different kinds of food? I'm not exactly being critical, I really want to know. I couldn't find protein content for vigor plus, but looking over what you're feeding in a flock with laying hens, you're short on the calcium unless you have oyster shell out for them. It looks like you're feeding 17-18 percent protein (estimating vigor plus at 30 percent) which is still a little low for three month old birds. You kind of confused me on the upper and lower, not sure who is where. If you have an older flock your 10 months olds could go with them and feed they younger ones the higher protein for at least another month. If I obviously don't understand whats going on, sorry, straighten me out.
