Hi everybody: My husband and I have been discussing the idea of putting a heater in the coop during the winter months. We are not sure what kind to use. My question is what kind have you folks used, or what would you recommand. Thank You. I will chicks of about 6 months old in the coop. Are weather can get pretty cold average temp is around mid 30's to lower 50's but we have knw to get down in the single digits and even in the negtives.
