Hi -- new to backyardchickens and loving reading the forum!! We are currently building a coop to house the 10 chickens we have a friend holding for us in her coop. We have a solid design and are making it super-dooper-predator proof (hardware cloth buried 10"); secure latches, etc. etc I realize there are a lot of ways to build a coop -- our design calls for a dirt floor -- it is not off the ground. We are making it large enough that it doesn't make sense. Any thoughts on this? Positives? Negatives? Thank you!!!
