We make sure both 5lb feeders(28 ladies and Roo) are full and let the chickens free range during the day. Though we dont let the ladies out till atleast noon so that we never again find a 29 egg pileup under the deck lol. I have a 5gal bucket full of oyster shells and only put in a few pinches ever week just to make sure they are getting enough calcium(though I practically need a hammer to crack the eggs now
). The birds get their grit from the yard as our soil has lots of rock(glacial run off I suspect). I agree with a previous poster that once they can forage they seem to leave the feeders alone until they go in for the night in which case they gorge themselves.
