I have eight buff orpingtons, two of which are roosters. The chickens are all about three months old and are not laying yet. I hear that buffs are great chickens and will become beautiful as they grow older. However, I have also heard stories about whole flocks of buffs that have stopped laying altogether. How long will my buffs lay? Is there anything that I can do in order to lengthen the time in which they lay? We just stared mixing laying pellets into thier chick mash, but I was wondering if there is anything that I could feed them that will increase thier production of eggs.
