For the breeds I'm considering (see sig), should I be concerned that my hens will burn out? Should I encourage them to go broody once in a while? I just read on another post that high productive layers can burn out early. Especially if they are hatchery chicks which is where I'm planning to get mine from. It never occurred to me that they naturally would need a break - DUH! As this will be my first venture into having chicks, I was liking the idea of getting my varried flock all from the same place. So I suppose my real question is this: how would I encourage a rest period? Since I'm in San Diego, our winters are pretty mild but the days do get shorter. Should I let the coop get dark to give them a break or only give them a little extra light? Our flock will be pets as well as egg producers and I would hate to cut their lives short or have reproductive problems just because we want more eggs.
