Hey id like to build a new brooder pen and coop outdoors for my current five two week old silkies. However id also like to be able to use it in the future for a broody hen or a larger batch of chicks. The basic idea is a structure with part of it made of wire and part of it closed in to provide shelter. My main question is how big shouodneach section be? I just want to make sure i do it right the first time
