I've thoroughly hosed out my large pen, and the maternity pen, changed bedding in nesting boxes, dusted everything in pestene including the chooks, and we still have mites!!!
All chooks free range in the day and are locked up at night, but it seems the grass around the maternity pen particularly is infested with the tiny menaces. I've dusted around it with pestene and DE, but they're still there!
How long do they take to die??
Am I doing something wrong??
