A nursing doe needs calcium and a lot of food. But I only fed grain with one or two does who seem to need it. Since a "scoop" can vary quite a bit, how many lbs or cups or something standardized is that? I always vote for more hay and less grain- it's so much safer for the animals and makes them happier.
You can change to alfalfa hay right now as cubes are just compressed hay. I would start putting hay in front of her and taper off the cubes by the same weight of hay.
I also don't know what all-stock is. Probably a corn-oat-barley thing? But it is not something my goats ever used so I can't say. But lots of good quality hay has always been my choice.
And I do the hay at least twice a day if she has cleaned up the hay way before the next feeding.
If you are speaking of disbudding (dehorned?) it is too late for the kids at 2 months- they probably have a fair amount of growth. It's usually done in the first 10 days or so. Dehorning can be done but it's a messy process that would scare me. I'd ask the vet.
I never banded or disbudded the bucklings as they all went off for meat before the were 6 months so I have nothing there either.
The kids The kids permanent vaccinations can start when they 8 or more weeks old. CDT at the least.
The kids should not be weaned until three months of age although I did wean a couple at a 9 weeks when their mom got sick and they did fine. Basically I have let the mom wean the kids, which she starts being serious about around 3-4 months. Depending on the doe, they will be totally weaned in a month from when she start getting cranky about them nursing.
You did not mention minerals which they need free choice.
Oh and welcome to the wonderful world of goats- but watch it, they are addicting.
