For me it's "what is the image in my head that I'm trying to turn into a photograph?" and "what steps am I willing to take to make it happen?" I like the idea of trying a setup like this, but don't find myself caring enough about birds to bother these days, and am happy to leave it to people more passionate about them than I am:).
6 flashes won't be necessary, the key is keeping the power low so they have short bursts and can freeze the motion. 1/16 or 1/32 power might have a t.1 time in the neighbourhood of 1/8000s or 1/12000s (it will vary greatly depending on the model, but some yongnuos and other flashes are measured here: Actual Measured Flash Durations of Small Speedlight Strobes). Less flash units means less light if you keep them at the same distances and power settings, but you can compromise with a higher iso or wider aperture. In the example above, he used f/18 and iso 160, so there's tons of room here.

If it's frozen wings you're after, I'd also go with flash(es).
The forte of a fellow I follow on flickr is freezing the frantic flapping of these fabulous flyers. For example: Hunting For Nectar | Flickr and look in the comments for a link to a detailed description of his setup. For this example he used 6 yongnuo flashes on 1/16 or 1/32 power, you could certainly make do with less especially if you're willing to up the iso. He also has a hummingbird album with photos taken in a variety of lighting setups that might be of some inspiration.
