Hello, We are fixing up a 6x6 resin shed to use as a coop. Planning a roost bar along the back wall with poop shelf below and nest boxes below that. We have 7 chicks of all kinds, black astrolorpe, buff Orpington, barred rock, prairie bluebell egger, olive egger, cream legbar, and I can’t remember the last one, maybe lav Orpington. Is one 6 foot roost bar long enough for 7 chickens? What size nest boxes do we need for these breeds, I was thinking just 2, is that enough? Thanks for your advice!
