The second line isn't actually sung, so I'm assuming it's some kind of translation of the first. As for the first line, I've no idea where to even begin parsing this (besides the word チキン). Does it actually mean anything?
My first thought is that it's either a completely different language or that it's some kind of "language game" similar to Pig Latin in English. Or it could just be nonsense words used to fit in with the song (the "translation" line merely there for a joke).
