Just to let you know - raccoons can easily reach through 1" so do make the corners solid. The staples will work - if you just nail a board over it, or better yet screw it on so you can just unscrew it if you ever have to remove the wire. I have to go back and rip all my wire off as I'm about to re-use that room and I'm going to redo it with staples (previously used U-staples) and board over to make it easier.
Snap - just if you have a latch that you can put a snap through, they can't open them as easily. It depends on what you use to close your doors. And yeah a coon couldn't do that.
I just found out from wire cages that raccoons can easily undo latches that it usually would take a human to undo. On one attack, when they killed all my show breeders, I thought at first a human had done it. I mean - there were about 18 birds dead. I couldn't imagine an animal doing it. Especially with latches undone.. Until I saw raccoon prints all over the place and talked to someone who said yes - they certainly could and would. Then it made sense the way some things were knocked over in high places... Just dreadful.
I gave up, but didn't have the chickens in my basement. I just kept the ones I had alive and let them all die of old age til I had two left. I got off of the boards (used to be online and whatnot a lot - not here though), stopped showing, all of that until my boyfriend showed an interested in them - and fate ran me into 8 little bantam chicks.
I tell you though - I like to free range my birds still, but the new show birds and these bantams - they're getting a coon-safe residence!!
LOL about lice and whatnot. Well I have a turkey in my bathtub right now, but that's different - she just had surgery last week and I SURE don't want her to be a permanent fixture!
