I've jumped in with both feet - got the chicken bug fast. I have 6 RIR/2 Roos and 4 Hens (ready to nest) and 9 (Think have 1 roo/8 Hens) Olive Eggers (what I've been told...will post pics and questions about that later/different forum). I'm trying to get my modified shed/coop ready for winter. My lovelies have free ranged all summer and have a summer coop they've enjoy and allowed me to "learn-along-the-way"...however, winter is much more serious a matter for me; especially them. Winters are VERY unpredictable here (Oklahoma). Last winter we had a horrible blizzard. I am modifing my shed into a winter coop. There are no windows, the door faces West, the roof is not sealed - the rafters 'lift' the roof (sorry, not sure on terminology) which puts the wind NORTH/SOUTH flow through the roof. I'm insulating the walls, but not sure what to do about the roof, ventilation and lack of natural light. I've thought about sealing and insultaing the rafters and putting vents on the EAST/WEST up high for ventilation. ANY help would be GREATLY appreciated!
