Adjust the gates or feeder run times so that feed makes it around the house or as far as possible to give the most feeder space per bird. If the feed only gets a few hundred feet each day, the most aggressive birds will consume a majority of the feed. Flock uniformity for body weight will be low and stay low because of the limited access to feed. Spread the feed all through the house to give all the birds access. Feeding time should be consistent day to day.
Birds are creatures of habit.
They thrive on the same feed times and are comforted by the same routine each day. The birds will adapt to almost any daily pattern, but will perform best when they get the same pattern each day. Many old-time poultry people wear the same hat or the same color shirt and pants each day. I can't attest to the value of this daily routine, but if you feed them on time each day you will reduce their stress levels and help them perform at their best. Calibrate your scales or have a knowledgeable person do it.
