How do you manage pest control? I have DE dust baths and I clean and dust the coop regularly with Seven, but I'm not sure what I'll do if/when I have a pest outbreak in my largest flock where the thought of dusting individual birds seems daunting. What preventative measures do you take and how do you handle an infestation once it happens? I assume each bird would need to be dusted but what's the more efficient and easiest way to do it?
