Possibly, sometimes.
While the donkeys people see off Waikoloa Road sometimes appear to have no water, they are watered twice a week and also have other access to water. Would they like more? Probably. But with as much green grass, even dry grass, they can go a long time without water and longer on "low water". Donkeys, like camels, can fill up all at once after working (bearing our burdens) a long number of days without water, If they fill up all at once from "empty" they can drink 13 gallons of water! I have to get out my calculator and figure the percent of body weight that is. ... later.
