What age and what outside temperature can I take my chicks outside to "play"? It would be supervised and only 20-45 mins at a time. I am not asking when they can go outside in the coop, just when they can start hanging around in the grass for a while. Spoiled buggers already beg to come out of the brooder so I have been letting them run around the bathroom and that is a messy time.
Any time. A mother hen will take her chicks outside after a day or two. If they huddle, they may be too cold but if they run around, they're fine.
