We are rather (too!) quickly approaching the point where we can start working on our permanent coop and run. Currently we have a 'TSC Special' that we are considering a grow out coop, ok for our 5 pullets but not what we want for full time use. We do have some parts that we could get, no floor, no roof, basically consider it 4 8'x8' framed panels. We would need some considerable work investment to make it any sort of useful coop for our purposes. We bought a house in south-east Wisconsin, on just over an acre. It is flat (nice!) but the wind has been fierce over the last weeks. Weather and wind comes in from west, sometimes northwest, sometimes southwest and sometimes from due south. We get the full run of weather here, -20 temps, with blowing snow in Dec-Feb 100 in July or Aug with humidity you could cut with a knife. I have worked outside (mostly in horse barns) over the last few years and have developed a pretty good appreciation for what it takes to care for animals outside in all weather. I have the freezing water problem solved (I think) which has been my biggest issue with the horses in the cold, horses, and chickens I gather are much better equipped for the cold than we are and personally I find being out all day in the cold properly dressed isn't too bad, as long as I can be out of the wind. Its going from heated house/car to cold and back that make it seem much worse. Thanks to all of you fine folks here I have discovered the Woods Coop and am very interested in these fresh-air buildings for chickens. My current considerations are: I have 5 chickens right now, 4 standards and 1 bantam silkie. We chose all breeds to be cold hardy and somewhat heat tolerant. However I have seen it mentioned that Silkies might not be best equipped to handle very cold temps in an open air type coop? Even one designed properly as Dr. Woods suggests? I would absolutely understand if that is the case, with the different feather design but I don't want to be paranoid for no good reason either. My other current consideration is size. I appreciate that part of the Woods design is the proper ratio and depth of the house, so that a minimum size is necessary to produce the desired air cushion effect of the design. What I haven't worked out is if there is some necessary ratio of birds to coop space? If I put 5 chickens in an 8'x12' Woods Coop, will there be any detriment to the birds to be in a fairly large space? I would need to probably petition to change the law or get some sort of exemption to be cleared for more birds so for the foreseeable future 5 is it. So basic questions for now are: Is a Silkie going to be ok in a Woods Coop in a Wisconsin winter? Is it going to be a problem to put only 5 chickens in an 8'x12' coop?
