I have 3 chicks, which aren't ready to go in a coop yet but my Husband and I want to get started on buy the materials and building a coop. I read that for the small size bantams that I have they only need 2 sq ft each. Is that correct? Now it that just for the coop? The run will be good size as we are using my large fenced in veggie garden for them. Also I have NO idea if I have females or males. If they are Roos then they'll need their own coop and run right? Thanks everyone. I'm new to all of this.
