I like to feed a 20% all flock type feed, with oyster shells on the side for the active layers, a bit of daily scratch grains, and occasional veg and animal protein....but my birds don't range.I forgot to mention her feed @aart,
they get scratch mix, and layer feed and lots of fresh veggies, we are on land so they are let out everyday for a while to eat bugs and grass
They need some extra protein to grow new feathers.
