Hello, this is my first posting (to any forum ever!) and question since my 4 chicks arrived 3 weeks ago. Their new coop is 'under construction' at a fast pace as they are quickly outgrowing their in-house accomodations (though I will miss them when they move outside..). My question relates to protection against predators in the run. I've read through many posts but haven't seen this exact question and I'm getting more nervous about predators the more I read so I want to do this part right..as much as is possible anyway. The coop and run are fully enclosed with 1/2" sq. wire and a metal roof and it will sit on grass. At the request of the local animal control officer I am burying wire 10-12" around the 4x8' run (he recommended 6"). The coop design I have recommends 2x4" welded wire for the floor but I'd like to skip this if my buried wire will be sufficient. It seems that the girls will enjoy scratching around a lot more without the wire floor but I don't want to put them at risk as I don't know what animals can dig below 10-12". I live in an urban setting but there are racoons, skunks, and a ground hog that visit my yard regularly. For all of you experienced folks do you think I can skip the wire floor or should I add it for extra protection? Thanks in advance for your help and thanks for this great forum! I've learned tons already..
