This is probably typical behavior, but I'm worried because it's going to get really cold. I have a flock of six (5 hens, 1 roo) who have grown up together and will be two years old in April 2011. I have a second "batch" of four; one girl who is 5-6 months old, three who are 3-4 months old who are with the flock and have been since they were quite small. Despite being "raised" with the original flock, they very much keep to themselves and are extremely deferential to the big girls. They eat last, quickly run away from the older girls if approached, sleep together and not on the roost and generally seem intimidated and respectful of the main flock. Now that it's getting colder, I have a huge problem in that the younger ones all race out of the coop and into the run in the morning, and basically stay out there until I let them all out to free range. I "think", but am not sure, that they get up earlier than everyone else and eat/drink before the big girls come off the roosts, but then they go out in the run and stay there while the big girls stay in the reasonably warm coop. I can put water & feed out in the run for them, and plan to do that asap, and I have hay bales stacked up as a wind break. But it is still bloody cold out there, and it's going to get way colder before it gets warmer. I generally let them all out to free range by about 11am. Is there anything I can do to "encourage" the two factions to assimilate and get the older ones to be nicer to the younger ones, and the younger ones to be less afraid of the older ones? My coop is big enough for 13 birds (I have 10, and 2 of those are bantams) in terms of sq. footage and roost space. My run is very large, but they do free range...though I'm not sure it's smart to let them out in very cold weather because then they are out in the elements for sure. Does everyone let them out if they are free range hens, no matter the weather? Should I keep them all locked up in the coop on bitterly cold & windy days, to insure that the little ones aren't shut out into the arctic, or is that inviting fights and pecking? Should I get a dog igloo house thingie to put in the run that they can get into, assuming they will in fact even go into such a thing? (And then, you watch, the older ones will want to get in the igloo.) Any help/advice much appreciated! Cold weather is a beast!
