If they were mine, I would continue with grower for a while. We have roosters and a mixed flock including peafowl. We alternate Flock Raiser and Layer. We feed a bag of layer, which lasts about a month or a little more, then when it's gone, we'll feed a bag of Flock Raiser, with Oyster Shell free choice, then when THAT's gone, we switch back to a bag of Flock Raiser again, and so forth. In the off seasons...fall and winter...we don't usually feed Layer at all. The roosters don't need a lot of calcium, and the peafowl do need the extra protein in the Flock Raiser, so it seems to balance out ok, we've been doing it that way for a few years.
