This is kind of a funny idea.
As other people on here mentioned, you'd need to hardware cloth your whole balcony for chickens, and I'm not sure how that would look. You'd also need to bring in tubs of dirt for dust bathing, which might be annoying. You'd also have to have an extra creative poop maintenance system.
Also as other said, for apartments I usually recommend quail, if you are looking for fresh eggs. They need less space and are very quiet, plus less likely to be frowned upon by the legal system. They still need dirt and stuff but much less of it.
Do you own your apartment? Does your balcony already have a garden?
