My black sex link gal was a few weeks when I got her in mid-November. I am still not getting an egg from her! I know all chickens are different, just like people, they mature at different rates but she is over 7 months. I thought black sex links were hybridized to start early. I really like this chicken. She's squatted for us for months. She is top hen back there and in charge of all the ladies. She does look meatier than the other layers. Perhaps she has a lot of genes from a stock of birds bred for the table? What are your experiences with black sex links?
