Kid won’t bond with herd

Hi. I have a kid goat that we had to raise from birth. She’s about 2 months now and we’re trying to get her to join the herd but she won’t bond with them. She’ll hang out with them in the pasture but doesn’t follow them when they move on. I don't think it's wise to leave her alone out there all by herself. I've tried putting her with one goat, we even bought a young wether for her to bond with, but it's not working. He likes her well enough and would bond with her, but she's totally indifferent to him. What do I do?
