Getting 3 NDs in the Spring - we're first timers. Thanks in advance for the help! Our goat pen will be about 50' off the back of our house. We have a hose bib that we could in theory use to run to the goat pen...what are our options for waterers...with 3 little (human) ones of my own I really want to avoid the added hassle of hauling water to the goats...there seem to be a ton of different bucket systems etc. What is best for a few NDs? Thank you!
