Where did you get the coop from? Several of us have asked and still there has been no answer. Why? Please let us know where you got it???????
Yes, racoons can definitely open your latches. The ones with holes in them, I'd suggest a lock with a combo or key. I have a hasp lock that has a swivel knob that locks with a key...when the knob is locked upright it cannot be opened, when horizontal it can be opened, plus it has a key for locking into the upright position. Got it at Lowes. This covers my two coop doors securing them. I also put a key lock on my nest box opening from the outside. Had problems with coons before and this time no one is getting in! Make sure you have vents at the top of the coop for moisture to escape...leave at least one of them open in the winter as moisture from the chickens breathing and from their poop creates moisture.
Beautiful coop! Congrats!!
