Fergie's Chickens

I've started enjoying the new Black Eyed Peas single, Boom Boom Pow. It's not the minimal instrumentation or the feel that someone did a few clever things in Ableton Live that impresses me the most. No. It's the line "I like that boom boom pow/them chickens jackin' my style" that I like. Fergie, the football pundit and singer puts these lines over with great conviction but, honestly, what is she going on about? Are chickens really jackin' her style? Answers please.
