yes keep milking that goat the more the merrier & 2 times a day should help...! but like milk in all animals it can be increased , but also that depends on how long she has been milking & if she just kidded in the last 6 months..? & the nutrition she is getting, so do your best on the nutrition side of things for her... i would look all that up to see whats the best to feed her, & you could increase the amount of milk you get.
have a good one
