Ah! Finally someone wants my advice! I suggest you prepare for more chickens then you originally thought you wanted. They're so much fun that it's inevitable that you'll want just one, maybe two more. Getting the coop prepared BEFORE bringing home the chicks will increase your level of enjoyment and free up the bathroom. You'll want to spend hours reading old threads on BYC to make sure you're prepared for any emergency, like that giant lump on your little chicks chest. You'll want to know why your lovely hen, that just started laying, is now losing all her feathers and won't lay any more eggs. You'll need to be prepared to answer all the questions that friends and family will have for you like how can your chickens lay eggs when you don't have a rooster? You'll discover that having a nice, safe, and cute (doesn't hurt) coop will give you a great nights sleep. Practice ignoring that look from your spouse that says "I don't want to hear any more stories of your darling little chickens and their adorable antics". If you want to buy a chicken diaper then do it, even though your best friend will think you've lost your mind. Have fun with your chickens and they'll teach you how to relax!!
