I regret not having a couple of mine disbudded, they got too big before I had time to deal with them.
def castrate boys.
I like to leave the kids on mum, for an easier life, when a bit older I seperate them longer each day and milk 'mum' once a day before letting them back together. because I handle the kids quite a bit then lead them out to the field, they are very friendly.
When it is time for kids to go, I let the mum out in the field as normal, take the kids away before she comes back in, leaving some nice hay or food to distract her, mine have never seemed bothered after that. (watching how the kids butt for more milk I think the dam is more relieved :-))
presuming you have other goats for her to mix with?
