Will be getting our first round of chickens this weekend and have to many options. Can I get some recommendations? I've met some great people that have helped me through all my petty questions and issues but I'm at teh final stages. I can seem to find people with 5-9 month old hens as they seem to be the highest demand. I have our "set up" for older birds (not chicks) but seem to be able to find 2-3 month olds pretty easily. Can you raise 2-3 months olds as older birds? Other than the obvious timing of getting them to lay eggs is their any advantage of getting birds at any specific age? PLEASE HELP
