I just brought home 8 chicks from TSC and tracked down the most likely hatchery they came from. As a result it became apparent that 5 are variations of Gold Sebright (one with a breed eliminating fault of a single comb). The other 3 are either Brown or Silver Duckwing OEGB. Are there any ways to determine which? Or is it a wait and see sort of approach? From my best guess they are between a week and a week and a half in age.
