I purchased this coop: http://www.thehenhousecollection.com/product.php?id=27 I plan to have 3 pullets and a 52 sq ft stationary run. Do I need to do anything else for ventilation or predator protection to this type of premade coop? The back flap is where the ventilation is, but I also ordered the wire-over-window option so that I can open the windows if necessary. I plan to latch the chicken door after the chickens are in the coop at night. I am wondering if I also need to put wire around the bottom of the coop to keep out predators. I don't see how they'd get in, but I've see photos of people with wire around the bottoms of the coop, so I thought I better ask. As far as predators in my area goes, we got a lot of critters that want to eat chickens: stray dogs, weasels, minx, hawks, fox, etc. Thanks!
