With the SQ buffs, you just have to wait till the time is right. They are slower to mature, lights and higher protein feed won't help. Or I never could get them to lay. The hatchery buff's will lay fairly early. That is what they are bred to do. Another problem I have is getting the girls to fat, I hand feed all my breeding pens everyday. About a cup each will work for my girls. If I fill the feeder they might lay one eggs a week. Hand feeding they lay about every day if they are pullets. Hen's don't lay as good. If I can, I cull all my hens and use pullets in the breeding pens. If your breeding plans worked good, you should have better young ones. Anyway that is my goal every spring, sometimes I will have a wreck. Anyone that says they always raises good ones all the time is not telling the truth.
