Kits&Kids,

On this homestead..we know exactly what you mean! We have been doing this for about 12 or so years now. Over the weekend, we were talking about poo-poo hits the fan time..we are confident n our goats and our Dexters to see us through.
We actually started this when we were still milking four girls..2 Saanens and 2 Nubes. Weezie..14 is a Saanen and still with us. We do spot worm if someone looks like they are getting into trouble..I doubt if we worm one in a year's time.
It takes a leap of faith and wanting to keep the animal..in this case a goat..as close as possible to it's original lifestyle. Would this work in a lot situation? I don't think so. It takes a wee bit of room..not oodles. And, I hate to say it, but it also takes culling and restraint on the run for assistance to the animal when it gets sick. Yeah, not a popular stance probably.
But when we (humans) get sick, a lot of us do go through some miserable days..without meds..and then heal. Goats, I believe, have the same ability to heal. It's all about the immune systems of the humans and the animals. If they are totally reliant on vaccines and meds..you HAVE to do it. But if they have hit a hiccup and come back from it..it has empowered their immune system. Again..just my thoughts..I'm no doctor or vet.
This method might NOT be for goats who have been raised for years the other method..I would say it would be a rough road to hoe with them. And it's not for those who want the most milk in the bucket.
Anyhow..for good or bad..we raise them the same way.
