We noticed a pretty significant reduction in our egg production last week. We are down to ~5 eggs per day as opposed to ~15. I suspected red mite at first, but today I went and checked a few of our hens and found these flees on them -- well at least I think they are fleas but I am not sure and I don't know what kind. Anyone knows what these are? What methods would you recommend to get rid of them? We have around 30 chickens and 20 ducks. Approximately 20 of our birds are layers, and the rest are between two and four month old. We have never used any proprietary products on them, if you suggest a product please let me know if you are aware of any risks. We would love to find a natural solution. However, we would greatly appreciate any advice. Thanks!
