Well, if it were me? Yes, I'd portion control. It isn't so much about the birds over feeding as it is about controlling waste, Waste on the ground, waste to wild birds, waste to the mice, chipmunks, squirrels, rats, etc. Yes, portion feeding is not that difficult. You'll have some trial and error at first, but eventually, you'll have them pegged pretty good as to their wants/needs. To the uninitiated, portion control sounds like one is miserly with the feed, and that isn't the case.
I begin with the adage that a hen (remember, I only have hens) eat 4-5 ounces per day, or a pound for every 4 adult layers. I feed a half portion at 6 am when I am doing barn chores, watering, etc. When I come back to gather eggs at 10 am, I check to see if the morning feed is gone. If I've fed the right amount, it should be just about gone. When I come back in the afternoon for the last egg collection, the feeders should be empty. They get another portion. That portion should be consumed before they head to roost. That's the trickier part. I want them to be satiated, but I do not want feed out overnight. Dialing it in, but I know my birds well. If I find I need to up the ration, the morning feeding gets larger, smaller if I find they aren't eating it all in time for the afternoon feeding.
