BBS fed within 24 hrs of them free swimming. I try and have a batch ready for when they are. I've found the first 24 hrs to be vitally important as far as feeding goes - once they're free swimming they've virtually used up their yolk sac, so they need fed!
There's so many ways of hatching BBS - I use a little tank as a water bath and hang an upturned half milk carton in there with an airline through the lid. After 18 - 24hrs pour the lot into a glass jug, position next to a light and siphon the BBS out when they swim towards the light! I've got a thread on here somewhere I put up about this - I'll try and find it. My method may have changed a bit since posting, but I'm sure the basics are the same... I've been using an eggs and salt premix for convenience - not the cheapest way, but gets great harvests.
