I live in East Yorkshire UK I had a bad case of mites last year. Cleaned the coop every 3-4 days with dilute jeyes fluid for a couple of weeks and now always use plenty of DE in the coop and mixed in with shavings on the floor of the coop as I have a few birds who always sleep on the floor...
I am so glad to read this.
I have 10 new hens, all young birds only been laying a few weeks. For the last 3 days I have been collecting 11 eggs per day. I have had chickens for the last 5 years and have never heard of this before, I thought either I was going mad or my cockerel was laying...
