Plymouth Rock Barred Rock Black And White

Is a Plymouth Rock and a Barred Rock the same breed?

Yes, there are several different colors in the breed (Buff, Barred, and White as far as I know). So they are usually just known by their color (ie: Buff Rock, Barred Rock, White Rock). The White rocks are not to be confused with the White Cornish Rock Cross, which are meat birds. Great birds!! Our 9-year-old Buff Rock still lays an egg every other day, and has made it through 8 COLD Vermont winters with no heat in the coop.

at what age can i tell the sex of barred rock? i have 3 to 4 month old one and was trying to tell, can i?
