Hi,
it depends. How are you creating this single braid? if you created the braid with Maya curves you can:
1. Convert it to Ornatrix hair using Hair from Curves preset.
2. Create a new hair object in a head scalp.
3. Use the Scatter node in this hair object to scatter the braid in the roots in the newly created hair object.
See the videos for Scatter node:

you can use the same workflow as the feathers.
