I'll preface this by saying that I live in Maine, we have long, cold winters! This is my first year owning chickens and I've experienced a bit of 'chicken math', so to speak. My flock currently consists of 4 LF adult laying hens, two 15 week giant pullets, and two 9 week old blue salmon favorelles (one pullet and one Roo.) The gals who are laying are accustomed to free ranging for part of the day. I currently have two chicken coops. One is 8x5 with an 8x6 run. The other is a 4x4 with an attached 8x8 pen. Both runs could be weather proofed to cut down on snow and wind. I know that chickens will huddle together for warmth, but I'm unsure of the best way to divide the flock for winter, having the baby Roo further complicates matters. I've toyed with the idea of attaching the runs and leaving the coops open on either end and letting them decide where to sleep. I've also considered adding two more chickens (if somebody twists my arm ) and that way four could stay in the tiny coop and 6 in the main coop. I'm still not sure when the rooster (9 weeks) will start mating with the hens. What would you do??
