Can you increase the time of free ranging? Mine are out from morning to night. I have 31 chickens. I am going through 50lbs in 2-3 weeks. Sometimes 4 weeks. They mostly eat the layer feed at night before going to roost. Seems the ones that didn't get enough while ranging, fill their crops before bedtime. Others I NEVER see touch the layer feed. Every once in awhile, I'll see a hen eating the feed during the day, but very rarely. I don't have a problem with egg shell hardness, nor production.
