I'm new to having chickens and I currently have about 5 light brahmas that are about 4 weeks old. I'm getting ready to order 25 more. I need to build a chicken coop. does anyone have any plans they could share on here? I plan on free ranging my chickens. I want a coop that I can move to different parts of the yard. I plan on giving them freedom to go anywhere in the yard and in and out of the coop. So here are some of my questions. 1. how many square feet per chicken do I need inside my coop? 2. Do I need a nesting box for every chicken? 3. Do I need to insulate the coop? if so, how do I keep the chickens from tearing the bat insulation down? 4. Is it ok to use pressure treated wood? 5. do light brahmas need heat in the winter time? I've read that they are very cold hardy birds, but of course everything has it's limits. thanks everyone for helping the beginner.
