If you can, make sure you have one rooster. A rooster will act as your guard dog and will 'try' to protect his flock. And make sure you can lock them in at night so raccoons can't get them. We lost one chicken to a fox before we got a rooster and lost one to a raccoon before we locked them in. Predators are your biggest concern. Hawks are the other one that can get them if you let the free range. Even if you lose some the eggs you'll get are worth every penny. They are just not the same garbage you get at the store. Plus it's fun the watch them. Good luck.
