I 100% agree with you.Not to contradict this advice, but if you're not looking to breed and sell for higher prices or show your goats buying registered goats is mostly preference. None of my goats are registered, but all are very healthy and serve the purpose that I need them for. We do not use our goats for milk (at this point - though we may try making soap in the future, too many other projects right now). We use our goats for land management - they help us keep the kudzu and privet beat back so that we don't lose our yard to it. They LOVE kudzu. Our goats are mostly pets that we breed here and there to make a bit of money to help with feed costs. We treat them more like dogs than livestock. It's all about what YOU are going to use your goats for. If you're wanting goats that will absolutely produce a lot of milk then buying from a registered line of proven dairy goats is your smartest choice. If you're looking for pets, registered goats can be expensive. It's a lot like buying purebred dogs vs. a mixed breed pup.
My advice is always visit the farm your goats are coming from - check out the conditions of where they're living, ask how often they are wormed and the farm's practices in regards to their health care - what minerals they use, etc. and only buy from places that appear to take good care of their animals.
For my situation I would prefer to have a registered herd, but I know of plenty of good goat breeders who aren't registered.
My goats are probably going end up being spoiled pets, but their main purpose will be for milk production on the farm. Getting to have kids and selling some to get some money back is bonus of course.
Once I contact a few breeders I'll definitely be seeing their setup and living conditions before buying any.
Thank you so much for your replies, I'm still a noob and this has really helped!
