Hello! We are picking up our 5 chicks (1 Brahma, 1 Barred Rock, 1 Wyandotte, 1 RIR and 1 Black Sex-Link) in roughly 4 weeks and want to start building our brooder. We have decided to just build it ourselves out of plywood and make a cover with wire mesh framed with wood instead of trying to convert plastic tubs or cardboard boxes because it seems like it will end up being the most cost efficient in the long run. My question is how big would you suggest we build it for those 5 chicks? We would like them to fit in there for at least 4 weeks until we can move them into their coup with their heat lamp. If they fit longer, then awesome! Pictures of successful brooders along with recommendations for inspiration are extra appreciated!
