What am I doing wrong?!? Feather picking is making me crazy!

Sorry my thoughts would be the same as Chris my first check would be for red mites in your house or lice on your hens.
2nd thought how big is your run and is it boredom. It is just too much of a coincidence that both your flocks have had the same problem.

Is there any way you can put a roost in the run? We have three, giving the hens a place to go when they are bothered. In our flock it's a safe haven from the roosters.
