This is probably a silly question, but as a newbie just in the planning stages I want to get it all right. Do chicks raised in a flock with a variety of breeds bond with each other or do they need others of their same breed to bond with? Do they know the difference? I really wanted to try a variety of breeds but didn't want to get just one of each if that is a problem. Is it better to focus on just a couple of breeds and get more of them? I was hoping to get about 15 chicks. I would love even more, but not sure I have the correct amount of space. Also, and this is kind of morbid, do most of you order more than you plan on ending up with to take into account possible chick mortality and predator losses?
