Did you see the mites?I treated the coop and all surfaces with a stronger solution then diluted and used on the birds based on the instructions. They all seemed fine this AM. I'll check back when I can determine the effectiveness of my treatments.
It is odd that only 2 hens seemed to have been affected by the mites. 3 other hens and my rooster didn't seem to have any issues. Assuming it's mites... Even the affected ones seem ok. Eating, drinking, ranging and laying.
