I am lucky that my daughter lives less than a mile away. She cares for the herd, milks (currently 6) and takes care of the chickens and dogs. But I help her, so she in turn helps me. I leave detailed notes and she does a good job. Does she do it exactly as I would? No, but it is close enough that it doesn't matter. The main things are 1. correct feed amounts, 2. fresh water 3. Hay feeders kept full. 4. Milk at about 12 hrs. apart. Anything else is just details and I don't care if she doesn't sweep the floor or empty the trash!
If I didn't have her, I could never go anywhere- I tried hiring a guy that had goats. He sure didn't treat mine well, didn't empty the water they somehow pooped in, (luckily, they had a lot of other buckets, but still!) Was to feed 2x a day, only fed once a day- doubled the amount- luckily they were only getting a small amount of grain, all were dry and mid pregnancy. Forgot to feed the chickens for the last 2 days, and left the barn lights on all week! What an electric bill that was! (Now, we have different lighting). So, I will never hire him again- He did get $25 an hour!
Don't make the mistake that some people do, you cannot leave out a lot of grain and hay for a goat and just leave. They can and will eat themselves to death!
To answer the original question, it can be difficult to find someone to care for your goats when you are gone. Goats are really a big investment in time and energy- but they sure are worth it! (except when you are in a hurry and they aren't...)
