Hello, I want to apologize in advance, I'm a brand new chicken mom & this is my first day on BYC, so I'm sorry for my newbie questions! I already had great help determining the age of my red sexlinks from you all! My next question is about these barred rocks (at least I think thy are BR)..I'm honestly not sure how old, I'm guessing about 3 weeks.. Based on the threads I have been reading I BELIEVE the first pic is a roo..and the second a hen? Could definitely be wrong..iam most definitely NO expert..what do you all think? I will add the first chick has barely any tail feathers, even less than my younger pullet BR..the second chick has tail feathers..TIA!
