some hatchery breeds can be a scarce version of the breed often times lacking key qualities of the breed. Wyandottes as a general rule for the breed are docile mellow birds, decent foragers, and not overly prone to aggression. I've heard of problems with buff orps too, hatchery stock that turned out mean and flighty!!! an orp! flighty!? You can get hatchery stock from fellow BYC'ers too so sourcing should always be important.
