I have 14 chickens all around 20 weeks old. I have an 11 pound feeder in the coup, and a 2 gallon watering dispenser in there as well. They are draining both in a 2 day time period, and trying to get in there to refill the feeder is becoming a nightmare. They swarm the door and act like they are starving. We can't free range the chickens due to our dogs (they don't understand that they aren't allowed to eat the chickens). Is this a normal amount for these chickens to be eating? None of them are laying yet, no molting, and they all look to be fat and healthy.
