Ok I just ordered 25 Buff Orpingtons from my pet chicken They will ship on Aug 11th. I need to know everything I'll need for when they arrive. My biggest question is how big of a brooder box to get. I have read so many different things, now I'm not sure. I have a 4' x 4' whelping box (I breed golden retrievers too) that I thought would be perfect, now I'm not sure it's big enough. Any help would be greatly appreciated
