That really depends on what the question is asking.
If it means chicken or the chicken egg, then obviously the chicken came first, since the first genetically unique chicken would have been born as a mutant from some other ancestral organism. It would be a chicken inside the egg of a non-chicken, and then it would subsequently begin laying chicken eggs.
That obviously beg(g)s the question

of what the "true" genetics of a chicken are, since there are obviously many varieties of chickens, but the general point is valid. In principle, however, one could decide at what point the ancestors of modern chickens began producing "true" chicken offspring as mutants from the parent population.
If it means the chicken or the egg-in-general, then it must be the egg, since dinosaurs were laying eggs long before there were ever chickens.
