Hello, is it really mites that cause my chickens to stomp while roosting - I sat there in the evening and was amazed listening to this rhythmic beat from these chickens in one area of the henhouse, then it started in the other part of the house. Some always thumped twice in a row, and at least five thumped always in the same order. None of them thumped at the same time, only one at a time. Within ten minutes all 40 chickens were keeping the beat! This went on for at least 30 minutes, then they all just stopped. I've had chickens for five years and I've never experienced this - very cool.
