When I get my first egg, I switch the birds to layer. I have several different ages so as of late I have been using All Flock or Flock Raiser depending on the brand. It is usually 20% protein. I have hanging feeders in my coops. I just add the layer or all flock to their starter/grower feed. I use pellets because the birds don't seem to waste as muck. Good luck and have fun...
