Frame it out with a 2x4 and cut some chicken wire easy! and its will be vented use screws with washers to attach fench if you cant hammer inside there keep food in a mouse proof container in storage
Thanks Zig Man. I'll see what I can come up with. Are metal bins good for mouse proof containers? I know if we attracted more mice my cat would sure be happy, but I don't want a lot of them around. I was thinking with the coop being so large and only having two to three hens (I'm not sure if one is a hen or a roo, I'll have to get rid of it if it's a roo) I needed to make it smaller so in the winter they could heat it better with their body heat. I read (maybe on the thread?) that coons can break through 1/4" plywood which is what I think the coop I bought is made out of. I know there are coons in the general area, and I see foxes a lot so I want to make sure they will be safe. I was thinking about adding some insulation and then using pallet boards over the top to not only make it warmer in the winter, but also give it more protection. We have up -10 or colder for a couple weeks here. Do you think all of that is necessary?
