I recently purchased a 7 month old dairy doe with horns. I have banded them with castrator bands and wrapped electrical tape around the bands to keep them in place. its been about a week. I checked them out today and I hardly see any difference. Looks like the bands barely made a mark. So I replaced the bands with fresh ones. How long does this usually take? Someone told me two weeks, but I can't see it working in that short amount of time. The reason I am banding her is because she is agressive and likes to use her horns on my other doe's. I'm afraid of her damaging my milk goats udders
