My sibling is the black sheep in the family. How can I help them?

You can talk to them, or even just include them into conversations. Find out things they like and try doing some things they like. See if they have anything in common with you. Anything that can make them feel like you care and that they are not alone.

He/she is your sibling. If you care for them, you can talk to your sibling and your family. Get things out in the open so your sibling won't be left out anymore.

Talk to your sibling from time to time and always take his/her side during arguments or problems. Ask your sibling if he/she wants to have a good talk, maybe even schedule the talk.

Make them feel like they're not the black sheep. Get them involved in Family activities. Get the whole family to make your sibling feel more like a member of the family rather than the black sheep.

Every black sheep needs just acceptance and physical support if possible. They can handle themselves just fine if let alone and accepted. Usually this "help" means trying to "white" them. And black sherp rebels. Black sheep needs freedom to make her own choices, no black sheep is stupid. Usually they are way more intelligent, and they refuse guidance from average joes. Acceptance and physical support (food, money maybe, home etc) Letting them be and letting them choose, to experiment themselves the good and bad in their own way. And they will learn in their own way, and settle down naturally.

Try to understand them, I had always felt like a bit of a black sheep in my family and when my siblings wanted to do something with me that they knew I was interested in, it really made my day a lot better. If you're genuinely interested in helping them, I think it's a good idea to get to know their hobbies and interests :)

You can try to talk to them about it. Ask your sibling how it makes them feel and if there is another way you can help your sibling fit in and make them feel better about themselves

I think that one if the ways that you can help them is to just be supportive of them. Maybe they're a little different than the rest of your family, but they need the same love and kindness and affection as everyone else. I would say to just be continually supportive of their passions, even if you don't understand or even don't agree. Support is a great assistant in growing closer to someone, especially a sibling. If you aren't supportive, they'll feel like you don't like them, and they'll truly feel like a black sheep, but if you support them and love them and give them attention, they won't feel different than the rest of the family.

Geez that's hard for anyone. I've definitely had experience with that and continue to. In my time, what has helped me the most is honesty. People talking to me, connecting with me as frequently as possible. Even if it is just one person, it helps build a community of people I can help support and who can support me. And whenever something big happens, like someone shuns your sibling, just talk to him/her. There's no point in sidestepping it. It happened. Talk about it, provide some support in their time of insecurity, and move on. And take your cues from your sibling. Sometimes your sibling will decide to confront people, other times let it go.
