Hello everyone, I have just joined your forum finally after being just a reader for quite some time. I have learned so much from all of you. I just had to go for it and join though because I have some questions too I think you all could help me out with. We are in Ontario Canada (zone 5a) which can have pretty cold winters. I was wondering if anyone knows how much cold the hens can take before they really don't do well. We have had hens in a non insulated shed for the last couple of years with heat bulbs hung in winter to keep the water from freezing but am I being cruel to keep them in there at such low temps? or should I be insulating our shed? What is the preferences of hens. Do they thrive in cold or not? I have never had a problem with egg production dropping significantly, but want to make sure I'm not putting them into conditions they shouldn't be in. We want to redo it to expand the flock next year but don't know whether insulated would be better or not worth the expense. Any thoughts would be appreciated! Thanks!
