He doesn't seem small to me? My doeling is about that size maybe smaller and she is 2 months...all goats are different and will grow at different rates, so I wouldn't worry Are the people telling you that he is small used to standard breeds? Or are they experienced with NDs? If you are personally worried he may be too small he might have stunted growth...is he otherwise normal? Eating, pooping fine? Are his eyelids normal color?
he doesnt look to small to me -- he wont achieve his full size until 2 years of age and even then he still growing till 4 years old.
I have a doe who is from a small sire and her daughter is bigger then she is! So not all Nigerian dwarfs are the same size. my herd is all varying sizes
with some help yes
I had a TINY buckling breed my largest doe with some assistance by me (I backed her up to a box and he jumped on from there). He was a horny little thing at that point so it made it easier.
