I have 4 large chickens 8-9 months old, brahma or wyandotte or mixed, 2 roosters, 1 hen, 1 questionable (hen head and hen tail with hackle feathers) who do not roost in a coop. There are 2 coops available to them but they prefer to roost outside on buckets. They originally roosted on an old sink setting next to the coop. We removed the sink, moved the coop there and added another door to the coop to make it more secure. So they scooted over to an old pallet. We built a large straw structure around the pallet added a roosting ladder inside and nesting boxes with a roof but the pallet was moved around and covered with straw so they moved over to some buckets next to the straw coop. So no one roosts in the straw coop but it's open and available. The rest of our flock roosts in a coop with 2 added on rooms with roosting ladders and is open for them to get in. So they have access to that structure too but choose to roost on the buckets outside. It will be 2⁰ in a few days with 20-30mph wind with gusts up to 50mph. The weather people say the rate the temperature drops will be dangerous. Should I physically put them in one of the coops? This is our first winter with chickens. We have a smaller coop with a small run where we are quarantining a rooster with wry neck; the whole flock was treated with amprolium for coccidiosis but we cant rule out injury causing the wry neck. Its 6 weeks later and he is better but still gets picked on if hes out with the flock. All this to say he has a heat lamp since he is not 100%. We also have eight 5month old silkies with a heat lamp in a separate fence. Any advice is appreciated.
