Hi there, My chickies are on the way (I think they are eggs right now!) and due to arrive June 14 from MPC. I can only get 4, and I am going to go shopping soon for a brooder light and things. How big should the brooder be for only a few? All the pics I see are of a dozen or more chicks. Thanks. Oh and I plan to keep them on our screened porch; it is warm here in GA so with that and the lamp they should be just fine.
