for people who love the littlest dairy goats
Congratulations on your goats and welcome to the group!
If you are giving them grass hay, you can't really overfeed them. If you are giving them alfalfa, you really should find grass hay because alfalfa is too rich for them. If they are still young and growing, they can use the calcium and protein in alfalfa, but once they're closer to a year, there is too much calcium and protein in alfalfa for them.
I don't sell any goats younger than 8 weeks unless they are bottlefed, but with wethers, they will probably be okay because they don't have to grow big and strong and start producing sperm or growing babies or making milk. Wethers tend to be very easy keepers.
They are skittish because they were not handled much. Sit down with them in the barn and let them approach you. Goats are naturally curious, and if you are not threatening, they will want to get to know you. Here is more info on that:
