It could mean that someone have (accidently or intentionally) put chicked bones on your car window. Probably you have parked the car near a fried chicken outlet. Also there is a possibility that a chicken was died or killed on your car window and only now you have noticed. Anyway, don't tuch those bones if you think it would be a bad thing, just put them away with a stick and wash.
A ladybird in English is also known as a ladybug or ladybeetle, a small red spotted beetle best known from the child's rhyme "Ladybird, ladybird, fly away home." In Shakespeare's Romeo and Juliet it is used by the nurse as a term of endearment. It was used in a similar way in Jonson's Cynthia's Revels, written shortly after.
"Ladybird" is a dialect variant of "ladybug." Both mean "Our Lady's bug/bird" and are one of the standard examples of a modern derivative of Old English feminine nouns without -s in the possessive. Presumably, then, a baby ladybird would be a larva or a pupa.
