I have a flock of 12, several different breeds, all standard size. I try very hard to let them free range at least 2 hrs every day and about three days a week they get out after 2pm (at least 3.5 hrs now but it used to be up to 7hrs) ... They NEVER stop scratching, chasing bugs, moving, working. They do dust bath in the run and in their pan but never outside in the yard or edge of the woods... Is this normal behavior? They have all the fresh greens, permium birdseed, laying pellets, oyster shell, grit and fresh water they want--so they aren't straving!
