I'm sure this is posted in another thread, but I have searched and haven't found much. So. Most of you have more extreme winters, I know, but I'm wondering how my birds will take it going from say yesterday that was 90+ to today that is 62 and going to get colder the rest of the winter. For anyone out of AZ, we do get down to freezing at night later in the season, and each year we get colder. I have one friend that brings her hen inside during the winter, but I'm still a chicken about the chickens (I'm slowly getting over my fear with having my own hens now, but I was absolutely terrified of them before I got them). I have irrational fears of ridiculous things like bugs and birds... So I picture myself trying to catch my two hens and being ripped to shreds by them, though I know they aren't nearly that bad. My girls did well this summer with shade and water, also did frozen water bottles on the hottest days, but I'm not sure what the best idea would be to keep them warm. I still don't have a closing coop like most of you do, I'm kind of old school that way. Their whole area is my version of their coop. They have roosts and nesting boxes which they don't use at all, and I tried to make a coop that was more open to put in the pen, but they hate it so I just used it as extra shelter for their food during our rainy season. I know that I'm kinda cold today, and it's only going to keep bouncing around until it gets really cold so I need to get to work on whatever to keep them warm this winter. I was thinking of something along the lines of this that people use to keep feral cats warm during the winter, but not sure my birds would go in it. http://www.pawesome.net/2010/07/diy-feral-cat-shelters-pet-projects/ Also thinking of getting heat lamps or maybe even a super safe portable heater to put in an area of their pen (I'd have to make a more enclosed area to make this cost effective. Any Tucsonans have advice?
