I loved my Nigerian Dwarves, they could be a bit vocal at feeding/milking time but other than that they were generally not too loud. I definitely recommend buying from a disease-tested herd, it’s easier to avoid those diseases altogether than it will be to get rid of them once they’re in your herd.
I know I’m a little late to the party, but I definitely agree with the others, the first doeling does look a little narrow, but you’d need updated pics to see what she looks like now. I would pass on the second goat entirely.
Another thing to consider is whether you want registered vs non, registered kids are MUCH easier to sell than non-registered.
