Its all fine especially when theres not yet any ladies in there.
Good luck with your new girls.
My advice would be that if its a second hand coop then treat the inside with either perservative or give it a going over with very strong bleach to get rid of any mites that might be hanging on.
Thats what I will be doing today with my new to me coop.
post some photos of your ladies once you get them
can definately recomend sussex bantams mine are awesome layers and lovely girls.
