So I don't need the tarp?! A concerned loved one keeps telling me it's too cold and she needs tarps and all kinds of things. This is not a person who has ever raised chickens. I have straw in the nest box and pine shavings in the coop.
Thank you for the compliment!
Chickens aren't bothered by cold until it's down below 0F or even lower. They're wearing built-in down parkas. We just have to give them a place where they can get out of the wind.
They are bothered by stale, stuffy air. Like all birds they have delicate respiratory systems and need abundant fresh air.
