Hi there! I am new to the forum and very excited to build my first chicken coop. I have been scouring the forum's threads and learning so much so now I have a few questions: 1) I have determined we want a raised coop with a construction cloth bottom to let the poop fall through. We live in the coastal San Diego area which is a zone 9 I think, so no frost. We have mild Winters and mild/warm Summers and I am wondering if I should design it open sided or solid with a window that can close? 2) How cold is too cold for chickens to be with a bottom that is open all the time? 3) I have a space that is 7'-0" long in which I would like to put the coop. If I am planning on having around 6 chickens, how wide should I make it? Thanks so much for you help!!
