Hard Rock?
Forum-Index → Help → Answered → Hard Rock?If you caught the Legendary, adopted its egg, and then HATCH it.. that's the only time that it'll break your chain, especially if you're hunting a different Pokémon.

It's kinda hard to catch, since the Legendary would randomly/rarely appear whenever you go and play on the Safari Zone.. considering that you own that kind of rock.
So, you would need to pay or enter the Safari Zone (again) whenever that Legendary didn't appear at all within your previous game (time).
