I bought my first chickens in March 2010. I currently have 20+ and approx 7 have started to lay. I noticed in looking thru Craigslist and the Farmers Market Bulletin there seems to be alot of "new chicks" and roosters/pullets for sale. My thinking would be to keep my current flock "as is" until the Spring but am thinking that experienced poultry owners may actually have a schedule of when they add to their flock and reduce/replace their flock...just wanting to know the thinking behind it in case I need to rethink my plan. I mean why would you have babies now with winter coming?? Why would you add pullets with egg laying decreasing when the days getting shorter??
