I am sure this question has been asked many times, so I apologize for repeating it. When can my rooster stop using the heat lamp? It looks like he's completely feathered and he can "jump/fly" out of his enclosed area when the top is off. My concern is that we've had some cold and rainy days and nights lately (in the 50's). I don't want him to be cold, but I also don't want him to be too hot! We are almost done making his house and pen so can I at least leave him out during the daytime?
