Mo,
I have a set of brooders I built that hopefully I will be done with today, If all goes well. It is a set of two, each is 3' X 6'. One has solid walls, the other solid and wire walls. Both open from the top. The one with walls has an opening to go into the other when they are placed nexgt to each other.The one with solid an wire walls can't be used by itself, as the wall that butts up to the other one is "open", with no covering on that side. Let me know and i can send you pics or you can come see them. between the two, I have 45 chicks and two turkey poults, but they are getting crowded now that they are bigger. This setup might be too big for what you need.....
If they suit your needs, I could loan them to you until next spring, when I will be needing them again.
