Yes I would definitely worm - especially if she has loose droppings (I have just had to do mine, it seems the mild winter has not got rid of any worms left on the pasture...

)
If you do, remember (depending on which wormer you use) it is 1.5 or 2 x the sheep dose that goats get and it would be best to weigh her. I have just weighed all of mine, and there were a few surprises...
You would get worried only if she starts to be choosy about her food and not have much of an appetite, which would be a sign of milkfever/hypocalcaemia.
Other than that - lots of branches, fruit/veg and a good dairy cattle/calf mix.
I don't actually weigh my feed...maybe I should.
