Can't figure out what's wrong. 1st thoughts was a bully, then to boredom but when the messy bottoms showed up my next thought was mites/lice. Nothing visible & have now noticed feather loss on underbelly of 2 hens. Dusting with
permethrin & have bathed 2/10 hens. Hope to follow up with more baths in a couple days (weather too cold now). Missing feathers are mainly on the neck areas. Egg production has decreased & finding broken/weak shells. Tried calcium supplement as recommended on another thread but no change yet.
Would MannaPro- Poultry Protector be a better solution???
