So anyway, I haven't had chickens in 15 years and the first experience was poorly planned and harmful to the birds. I want to do it right this time. How big a coop should I build for 25 stanard breed birds? I'm only planning to overwinter about a dozen. I also want to divide so I can rotate layers every 2nd or 3rd year. I have time as I won't start the new flock until April. Also, any suggestions on where to buy day olds? I want all pullets, as I live in a somewhat urban area now.
