This morning I got my 25 baby chicks in "Australops". I've got them in a brood box with a Red light heat lamp, water food, and they seem to be doing fabulous! My question is that tonight it'll get around 48 degrees, they are out of the wind, but will that light sustain the heat that they need through the night? The brooding box is approx 4' long, 3' wide, and 3' tall. I stuck my hand under the light, and its really warm, and like I said there doing good. Thanks I did line the whole bottom of the box with hay.
