so this will be my first winter with chickens and turkeys (I've overwintered ducks and geese before.) We're in SW Missouri so I expect freezing, occasional snow, and probably an ice storm or two. local weather data shows the mean low temperatures are a few degrees below freezing during Dec-Feb, with mean highs in the mid-fourties. here's the setup we're currently using, looking for feedback on if we need to make a change. what we've got is a LARGE kennel building with inside/outside runs. the roof overhang fully covers the outside runs. the run fences are about 6' high and the top bar is 2" square metal pipe. We've added some 2x4s crossways to the pipe, and some heavy branches stepping up height-wise across the back of the runs, however the majority of the turkeys and all the chickens prefer to roost on the pipe, not the wood. the area is fully covered from the top, and the slope of the roof is good, so even in bad, windy storms, the area they roost in stays dry. it is, however, entirely open to the outside on 3 sides so it can be windy. the birds free range during the day, and roost on the tops of the run fence at night. there are dog-doors in each run so the birds *could* go inside the building (which is still ambient temp, but mostly out of the wind) but while they occasionally go in there, they *always* roost outside. when the birds roost, they are getting their feet clear up inside their feathers so their toes are covered, but they are perched on metal rails. they're all in good weight, and fully feathered (we just finished with the majority of turkey molting and none of the chickens seem inclined to molt.) so. here are my questions... 1) will they / can they get frostbite on their feet from the metal rails once it gets colder? do I need to prevent them from roosting on the pipe? 2) If I add top wire, I can prevent them from roosting on the metal rail but still have roosting space on the branches and 2x4s. they will still be outside (protected from rain /snow, but not always from wind). will they freeze / get frostbite from roosting outside if protected from rain / snow? 3) do I need to make them roost inside the kennel building? it's not heated, but it is relatively wind-free.
