Bad wrap for Cornish cross/Cornish rocks
A bad wrap is an unappetizing sandwich made of fillings wrapped in a tortilla. A bad rap—otherwise known as a bum rap—is dishonor resulting from false accusations or trumped-up charges. No hyphen is needed in this noun phrase.
There’s also bad rep (where rep is short for reputation—an abbreviation that dates back centuries), which makes more sense than bad wrap. To have a bad rap is to have a bad rep, but bad rep appears only rarely, and some readers might interpret it as a misspelling of bad rap.
The rap in bad rap is related to an American sense of the word dating from the late 18th century—namely, a reprimand or a criticism. It’s closely related to the rap in rap sheet, which refers to a list of one’s past criminal offenses. All these senses of rap probably descend from older senses relating to blows and strokes delivered as punishment. The fact that rap sounds like rep might also have contributed to the modern sense of bad rap.
