I keep hearing DO NOT FEED LAYER TO PULLETS UNTIL THEY LAY. Then some say it is ok. What gives? I have 10 week old pullets and 1yr old hens I am fighting them both trying to keep them out of each other's food. You know the greener grass thing. I am almost out of starter The FEED Lot does not sell anything in between except "Game Cock Feed" what ever that is. WHat to do?
