Hey Bee; I would have liked to have done this right from the get go but their coop wasn't ready yet. Can you tell me the coldest temps you've brooded chicks at outside there in WV? I suspect we have similar weather. My next batch of chicks is due in mid June so no worry about temps then, lol but who knows for next year? Can you tell I'm a new chick mama?. I love trusting GOD to take care of things. He does it so perfectly
The coldest was 20-30s at night, 30-40s in the day. They do just fine and fledge out quickly, adapting to the temps easily. It's in that setup that the HP mama really shines, as the chicks will duck under it to warm up just as they would with their own mama, but then they are back out running around and exploring their brooder, eating, drinking, etc.
Another neat thing about keeping them outdoors is that their mess is all outside, you can use a nipple waterer there and that helps with the mess, and they get exposed to the germs in the coop environment when it's the most important. I even brood mine now on the existing deep litter the flock has been using so they get the same exposure to germs that they would if they had a real mama. I never get coccidiosis here and I think it's a direct result of that early exposure.
Then my chicks are out of the brooder and ranging by 2-3 wks, eating with the flock and putting themselves to bed under the HP brooder each night until they no longer need it.
