It's all going to come down to your preference. Just start looking around at the various breeds and decide what you like. There are some real beauties in both sizes. My preference is big chickens but that's just me. And if you get a nice coop with lots of insulation so it's sort of soundproofed they make most of their noise when they're frightened or laying eggs so if they're in their nice house when they're laying the eggs and no one ever frightens them you should be good to fly under that radar. They will come running out to talk to you every morning when you let them out and bring their treats and they'll tell you all about the lives and inquire about yours quite loudly but they settle down quickly when you give them something to put in their mouths.
