1) If I wanted a build an only for them at night coop for 2 chickens, would 4x3 be okay? 2) Is keeping chickens inside detrimental to their health? 3) For 8 (one bantam) is an 8x12 run okay? 4) We have raccoons, coyotes, foxes, dogs, and cats in our neighborhood. Yay. When it comes to the run, which they would only be in during the daytime hours, so from about 7ish AM to around 5-6 PM, before it goes dark so I can make sure they are safe, is it okay to simply place a run, without a floor, on the ground, or would I need to secure it somehow? They would have access to the coop if they felt harmed at all. The run has chicken wire over top and sides. 5) For 6-8 chickens at night, is a 4x6 okay, or should I go 5x6? 6) I would like to keep out predators, obviously. I plan to just go with a plywood box basically (boxes and roost on the inside), complete with a hinged top so I can get access to the whole coop. I plan to secure it with a lock that has a number code, since apparently raccoons are real handymen, same with the little coop door for the chickens to go in and out. I assume that even they won't be able to figure that out. The issue I am having is with 1/4 inch plywood. For a hungry coyote, would that be like attacking cardboard for us? If not, could I go for 1/2 inch, or maybe the 1/4 with oak boards? Thank you so much!
