O.k. first I want to apologize for not looking up this information first before I ask the questions, But I am working overtime and home for just a few minutes so I just am trying to get a quick answer on this subject. I am only a chicken momma of 6 months now. I live in Missouri, so not so hard winters. Will my chickens lay eggs all winter? or do they quit when it gets cold? Already have skipped days since the temp dropped. A heat lamp to be added at night or not?Or when it gets below what? Feed more corn during cold temps correct? Any quick links to how to prepare chickens for cold winters. Thank you in Advance, I am sorry I just haven't had time to look up.
