I'm new here and new to raising chickens. I live 9 miles north of the Ohio river. I have 6 birds. Not sure what kind. 3 reds, 1 black, 1 white, and 1 yellow. Bought them just after Easter as chicks, and they are supposed to be all pullets, but I suspect one, as it is looking mighty cocky to me. They should be egging in September or October. I have been feeding them a laying mash and they have access to marble grit, driveway stones, oyster shell, blackberries, twinberry honeysuckle, and an amazing amount of bugs. I have also given them a few cobs of fresh corn off and on the cob, as they really love it both ways. I notice that they always eat the corn, but sometimes, they don't seem to care about blackberries. If they are provided with a variety of food, can I trust them to peck out a balanced diet, or am I giving them the chicken equivalent of pizza and mountain dew when I serve corn?
