I have two unregistered Nigerian dwarfs and I have really fallen in love with the breed. I would like to increase my herd but with registered stock. The problem is that all of the ones I'm looking at seem to be registered differently. Most of the does that I like are registered with NDGA whereas the buck I'm in love with is AGS. I know you can register a nigerian with ADGA if they are already registered with AGS but not with NDGA. So my question is which is better? Or which registry do you perfer? Thanks!
