I agree. One flock could be roosters only, the other flock could be hens with no roosters, or maybe with one rooster.
A common guideline is 4 square feet of space per chicken in the coop (that is where they sleep at night, and where they hang out all day in bad weather), and 10 square feet of space per chicken in the run (that is where they spend most of the day when the weather is nice). Given that roosters are often bigger than hens, you may want to provide even more space than that. People in extreme climates (hot or cold) often end up with modifications of those guidelines: cold climates may need a much bigger coop (because the run is unavailable for so much of the year), while hot climates may have a roofed run and no real "coop" at all.
They still taste like chicken
Sometimes a person's feelings will change over time, so I suggest you re-check your views every few months as they grow up. If your views change, then you can decide whether to do anything different. And if your views stay the same, then of course you don't have to change anything.
