What’s the Difference Between Hybrid and Heritage Chickens

I’ve been reading about the difference between hybrid and heritage chickens, and I’m curious how their traits compare in real backyard flocks. For example, hybrid breeds like the Cinnamon Queen are known for their productivity, but I wonder how much breed type really influences things like temperament, lifespan, or even practical details such as cinnamon queen chicken egg color. Do you find hybrids more reliable than heritage breeds, or do you prefer the traditional ones for long-term flock management.
