Just another thought on it...I agree with the advice so far....but you may want to first just feed the "treats" so they know they like it. I have goat grain. I shake the bucket and feed it. They are smart and social and will quickly learn you are the "treat buddy". While they eat the treat I just had the treat closer to me until I would pet them while they ate. Goats love to be loved, in a short time you will have them "eating out of your hand".
WARNING...Long ago, a friend fed her pony sugar cubes and kept them in a hind pocket...thought it was cute that the pony tried to get the cube on it own until one day when it got hold of more than the sugar cube

Goats can bite (normally they don't) but they will also knock you over to get the treat. Watch funny videos of kids at petting zoos

, Sooooo also teach manners. They are smart and will learn that they like you and your treats. They are easy to tame, but harder to train to undo a bad behavior.
I have mine get on top of the goat houses to get the treat, so they don't jump on people. One puts her feet up on Peter-John's lap when he is in the wheelchair for him to feed her. Then "off" to get her down when he is done. And she knows "play this game right...you play it more often."
Congrats on the new "kids"

Did you post pics?

Goats love to have their pictures posted on HT. Honest they do!!!!!
Plan to laugh loads with your new babies, as goats are like a piece of God's humor in action.
