You might consider laying an "apron" of 1/2" hardware cloth on the ground going all the way around the outside perimeter of the pen. Somehow attach it to the boards on the base of the pen. Put it out about 15" from the base of the pen. The apron will prevent critters from digging through the soil to get inside the pen ie; rats, possums, coons, dogs etc...
Very Nice... Only one suggestion. I live in Florida too near Ocala. You may want to put more vents in the coop for ventilation. Do you have any wire around the bottom to keep predators from digging under? It will be awhile before your birds are discovered. We have a farm swap twice a month. If you ever get up our way stop in and say hi. Good luck and have fun...New to this. We are in Tampa. We have 3 Black Australorps, 2 Isa Browns, and 1 White Leghorn. They've been in the house for 3 weeks. We'll probably move them to their permanent home in 2 more weeks. Learning as we go and enjoying the journey.
