Herd goal???? without paper work the unregistered animals are considered grade does and the billy should have been wethered...JMO...naturally your decision should be based on the animals taken singly not as a "package deal"....No one will tell you to buy anything, registered/unregistered, without a "hands on" session with each animal...You have to first have a herd goal in place then go to look at only animals that fit into your plan...When you look at a prospective animal look at its structure,condition,moblility,coat,teeth,udder,basically the entire animal, with not only your eyes but with your hands as well...Buy the best animal you can afford that fits into your plan...I wouldn't suggest buying a group of does because someone told you its a good deal...sounds like an auction barn...Important: ask the owner to look at any records he may have about pertaining to the particular animal, verbal records aren't too believable, ask if he owns the dam/sire/siblings of the animal....an honest seller will tell you what he has and show you what you ask for....So what's your herd goal?
