Eclipse teaches divination (of all kinds, it says) and herbalism.
Penta Magic teaches herbal remedies and divination.
Second Sight teaches herbalism and divination.
As far as I know, those three covens are open to applications currently. I didn't specifically see one that said anything about chaos magick, so I encourage you to ask the priest/ess or council of a coven you are interested in to see if they cover it in their discussions.
As for the family-aspect, I think a lot of covens strive to achieve that and to a person who is in a coven, they would most likely tell you their coven treats them as family. To get a better "feel", though, perhaps spend some time talking to the priest/ess, council, and/or members to get to know them more and see how compatible you are with them.
Best of luck.
