Its supposed to be like -10 today and later tonight. My fam is worried about the chickens. I personally think they will be ok. They have a coop to go in and straw in the run and really really deep shavings inside. We added some more ventilation, and although its not like a huge amount its much more than before. There are 19 birds so they can huddle together to stay warm if needed. Should we put a heat lamp in there? I think they'll be fine, and I'm afraid that if they are exposed to heat for a while, that when we go to take it out when it's not so cold, that they will be even more cold than before. I don't know though. Thoughts?
