So I just purchased my first 3 chickens (1 barred rock, 1 RIR, 1 australorp) and the seller made a statement that I need some help understanding. All the chickens i purchased (approximately 5-6 months old now) as well as maybe a dozen others, hatched at the same time. Same time, same hen, same rooster, producing at least 4 different breeds. How is this possible? I know labs can give birth to puppies of different colors, is this the same principle? Thanks in advance for any insight you guys have.
