If it's too cold to spray the coop, then dust it along with the hens.I have been spraying the entire coop every weekend. I did. stop though due to negative degree weather. I have been dusting them but the stores haven’t been stocking the dust and it’s been hard trying to get a new one. What’s the best Poultry vitamin I can give them? What kind of ointment should I give her?
The mites are likely contributing to the facial swelling and eye irritation.
