hi there. i am new to this website and to raising hen. i just got myself a brand new, insulated coop and 4 banty hens. the thought of winter scares me a bit. the questions that enter my mind are : how do i keep the coop clean and dry, is a heat lamp useful for a small coop, will the hens still go outside winter time and will they continue to lay eggs... we live in north ontario where winters can get down to -40 celsius on ocassion. please help.
