May seem stupid but i can't find any injectable or water soluble ivermectin online that is cheap. Can they drink the pour on type if i dilute it in water and keep it well stirred to prevent it separating? If so what ratio would i dilute it to? My hens all seem well but sneeze occasionally and sniffle like they have a cold. I have read that the ivermectin will treat them when diluted in water. I have also heard of antibiotics but don't know what or where to get them from. Any help would be great. THANK YOU.
