I've noticed my flock doing a lot of cleaning with their beak. No scratching, just pecking around a bunch during down time, especially when it's hot or they're bored. There is only one that currently doesn't put up a big stink if I try and hold her, and I was unable to find bugs on her. I have seen some things flying around my roo from time to time, but they looked like gnats. They have fresh pine shavings (the new coop is only 10 days old) and a layer of DE and I also just added a little bit of poultry dust as well, just to be safe. I'm asking here first, because I'd rather not traumatize the flock by having some old fat guy ( me) running around trying to catch them so I can inspect for bugs. So how much of that kind of cleaning is normal?
