Hello, I am new to this world of chickens. So new that I haven't even got the chicks yet! My daughter has a henny penny program running in her preschool at the moment and we have committed to getting 4 at the end. We are currently preparing our backyard for their arrival next week. My question regards picking the sex of the chicks at such a young age (1-2 weeks). We (and our neighbours, I am sure!) would prefer females but as they are all yellow and fluffy it is hard to determine their sex. I recall an episode of "Friends" where Chandler blows on the genitals of their chick in the hope of determining its gender beneath the feathers! I wonder if anyone can advise me on ways to detect between hens and roosters??? Thank you.
