Hi! So, we had our weather change drastically from warm and sunny to freezing ice and snow a couple weeks ago. When this happened the goats passed around a little cold which I treated with an herbal tincture mixed into their feed pellets. Most of them who got it only had it for a day or two then were fine. One goat kept coughing a dry cough so I gave her and another ivermectin past for lungworms. A week or 2 later Both now have a runny nose with thick opaque snot- very slightly green. One of their kids just developed the snotty nose yesterday. All 3 of these girls are acting totally normal- eating fine and full of energy and all 3 are most likely in the early stages of pregnancy. The rest of the herd is clean nosed and doing fine. How should I treat this other than going to the expensive vet? I am worried it might be pneumonia. Going to put new bedding in the barn today for good measure and would love to hear suggestions. thanks!
