Goats do just fine being weaned at 6 weeks as long as they are eating grass or hay. Just because they sold them young does not mean they are not good goat owners. Maybe they are , maybe they are not. But it is just as much the buyers fault for buying them without their research as it is the previous owners. I have goats and take very good care of all my goats. In my opinion, and solely my opinion based on my own experience, and not what I read from the internet. I sell my goats around 8 weeks, but would let them go at 6, if some goatlings are going together. The longer they stay with their moms and the herd, the harder it is on them when they are sold. The younger they are sold the more likely they will bond with their new owners and new goat family. It is hard to let them go at any age, but that is the way it is. And if people did not breed and sell animals then no one would have the experience and happiness that they bring. Saying they misused them because they were sold young is an opinion that may have been based on incomplete information. The goats that I keep and allow the mother to wean on her own often nurse until they are almost a year, of course they eat grass and hay throughout, but they are still nursing.
