I need advice or plans for a decent coop to fit about 4 Cochin's and maybe 2 standards, that can be transportable but I'm not looking for a simple chicken tractor, I want a decent coop for my birds, but I also need top security. I have coons (a pack of 6 thug, dog sized coons that have matching leather jackets,) and possums whom im too not worried about, but don't want them in my coop. I already know I have to move in a year so need an appropriate coop. Thank you friends for you advice and ideas.
