As a newbie, I was stressing out about doing the mite check. I was worried the girls would squawk and jump off the roosts......but it was a total non-event. If I can do this, anyone can: I just shined the flashlight on their little bums, and gently started lifting tail-feathers until I could see the vent. I had read that you would be able to see the mites running for cover. No mites~ just pristine little vents. I did not include pics, as my girls are WAY too modest!
