Ok, So I'm getting ready to get my coop ready for winter and this will be my first winter with my girls... With that said I have yet to winterize, and im looking for helpful advice. I have 5 urban birds 2 RIR, 2 BR and one EE with a fairly large uncovered 20'x15' run and a small covered run 4'x8' and their coop being 4'x4'x4'plus...I have 2 exterior nesting boxes and 2 roosts (the lower one never gets used)... My questions are fairly common ones regarding ventilation. I have a total of eight 3 inch diameter holes near the top. 4 on each side for cross ventilation. As you can see from the pics the roost they prefer is fairly close to the vents, Is this too close? Should I reduce the number of vents and lower the roost? I live in the Pacific Northwest and it gets chilly/damp most nights but only freezes for short periods in the coldest months (Dec-Feb). I have noticed they are eating a ton of feed which I believe means they are cold...(no worms) I also have two large windows across from each other that are not sealed... i plan on putting some moulding up so it minimizes the draft but is this even needed? any input is much appreciated thanks in advance!
