I have two Nigi bucklings that will be three weeks old tomorrow. I can barely feel bumps on their heads.. is it possible they are polled? Or, do their horns grow in slower than the larger breeds? The buck I used for this breeding does have some polled ancestors - he is not polled. The dams do not and they are not polled. I don't want horned goats but don't want to disbud if they are polled, obviously.
