Goats do better if they have access to mineral licks, the best to get for them is the Red Rockies (as for horses). These have added Copper - v important for dairy goats - but best to put them up in their pens out of reach of sheep.
Make sure you get some of their feed and hay from the previous owner - adult goats can be difficult to get used to new food, get a list of their favourite treats and preferably get the previous owner to worm them on leaving her farm (or do it when they are in your pen, but don't let them outside), make sure you know when any booster vaccines are due, let the previous owner show you how to trim feet, unless you know how to do it...
and don't let them out into their new field until you are sure they are worm free, and they are used to you enough to let you catch them for coming back inside.
Ask which side they were milked on.
can't remember anything else just now... too late, bedtime.
