I have free range chickens with lots of dusting space and have discovered lice. I generally check/dust them in the with and give them ash to dust themselves because they spend more time in the coop, but summer I generally don't have an issue. I just picked up a hen and the nits are aweful. I'm feeling bad I haven't checked in a while.Yep, this is another reason why free ranging your flocks makes so much sense. It isn't a issue at all. The flock treats themselves....less stress for you and the flock, and healthier less stressed birds that lay better and have their freedom. Kinda win, win, win....you, the flock, and their health.
The flocks best interest and the eggs they provide, is why we have a backyard flock, eh?
