My friend who just got stationed in Sicily is asking me about getting a flock of hens at his place. But apparently, there's NO ground at all. So he's going to have to keep hens in a coop with no access to dirt, grass, bugs, anything. I've never thought of doing this before and don't know the practicality. I know that in commercial operations in the states they don't get access to ground, but then the behavior problems crop up. Has anyone ever tried this? Got any advice? Should they just not get chickens?
