I completely agree with Wisher. Heat only when they're chicks and only when they're really young chicks. I used to follow the 95 degrees for a week and then reduce by 5 degrees a week until you hit ambient temp. That is way too long with a heat lamp! And I changed the instant I saw my broodies and their chicks running around in freezing temps, enjoying life. I have to say I think they do feather out faster, and are healthier when handled like that. I make sure to watch them of course and adjust the heat as needed based on their behavior, but mine are usually off the heat by about 2 weeks, when they have all their wing feathers and their chest and back are starting to come in. I also move mine out to the coop around 4-6 weeks, regardless of temp, and I generally hatch in January, and obviously live in Maine.
This is so awesome! I can't wait to see the pictures, also.
And you haven't had a frost, yet?
