Can the frozen chicken legs sold in the vegetable market be eaten often?

Frozen chicken legs sold in the market can't be eaten often, because they are processed by instant chicken. In order to shorten the growth process of this kind of chicken, merchants use a lot of antibiotics to enhance the resistance of each chicken and improve its quality materials. On the other hand, the freezing time of frozen chicken legs is uncertain, because many things will be treated accordingly after freezing. The frozen chicken legs on the market are probably the kind of zombie meat.
