Why is chicken suggested as a solution
The hints are not "suggestions".
They can contain translations that are not appropriate in the current sentence, like dictionary definitions.
They can jog your memory or remind you of the correct spelling, but you (the learner) are solely responsible for picking the correct hint, or (in rare cases which we try to correct as we become aware of them) for determining that none of them are suitable for the current sentence.
That said, there are accepted translations for this sentence that include the word "chicken". What was your entire sentence?
Did you report your answer as "my translation should be accepted"?
Are you sure that you had a translation exercise and not a listening exercise?
Do you have a screenshot that shows the question and your answer? If so, that would be excellent -- please upload it to a website (e.g. imgur) and tell us the URL. Thank you!
