I have 5 hens - 2 reds 2 buffs and 1 barred plymouth rock. 2.5 yrs old. About 1 month ago, they had a mite infestation which I cleaned the coop & pen, sprayed with Poultry Protector (manufactured by ISP-care free enzymes, inc.) I also sprayed the hens. Now, they are loosing thier feathers (bald spots), not eating thier feed (will eat greens, fruit, scratch), losing weight, laid no eggs since. I am sooooo worried. Please help,any advice would be most appreciated.
