Think about feed and poop when you're choosing chickens. Here's our experience: We've been doing the BYC thing for 2 years. We've had Wyandottes and Golden Buffs (or Buff Orpingtons, can't remember). The Wyandottes layed medium/large eggs at 4-5 a week. Our new Buffs lay HUGE eggs every day. They're amazing. We also seem to go through twice as much feed and water for the same birds. We also seem to step in poo ALL the time. It looks like a small dog left some of the piles. The coop needs cleaned out weekly instead of monthly. Point is, if you let them free range, you have a small backyard, and you don't like poo everywhere, then give careful consideration to the breed. A heavy layer is fun to have, you get lots of eggs, but you might be better off with 3 lighter breeds that leave less of a mess. So we're going back to the skittish but easier Wyandottes. The buffs will hopefully make a nice stew.
