My personal experience, about 50% of the chicks we got last April from TSC were not the breed they were supposed to be. For example, we got two chicks that were supposed to be silver laced Wyandotte's that ended up being spangled hamburgs (not even a breed they advertised as having...)
Not sure some of the folks that work in the stores know the difference between breeds tbh - and neither did we at the time. We were chicken newbies and really had no idea we got the wrong breeds until they were probably 9-12 weeks old. We love our birds, regardless - but I would not necessarily rely on the 'experts' at TSC if you're trying to get/avoid very specific breeds.
I have an Australorp (who TSC had in the Jersey Giant bin...) that insists on informing everyone in a 5 mile radius when she is planning to lay an egg - she is very sweet and docile, but is rather noisy. And a blue jersey giant that 'talks' more than any of my other chickens, usually very loudly and I am pretty sure she is always mad at the world
