I have 18 hens of different breeds that semi free range. They stay in a large electric fenced area that I used to keep sheep in. I feed them commercial layer pellets daily but they act like they are starving. When they see me pull in the driveway or they see me outside they literally line up at the gate and act like they are waiting for me to feed them. When I do feed them they act like they can't get enough and I feed them 3 to 4 big scoops (a large scoop that is a horse feed scoop). I'm not sure if I should feed them more???
