I have 6 Golden Comets and 3 Black-sex-linked chickens and they are 15 1/2 weeks old today. I keep looking on the internet at pictures of chickens around 16 weeks old and mine look nothing like them! Yes, I am looking at golden comets and black-sex-links... The images show medium-sized deep red combs and wattles but mine have small orangesh-red combs that are very short and wattles that aren't even hanging yet! Am I doing something wrong? I feed them everyday, they have fresh water all the time, and are very happy active birds. Why are they not growing like they should?!?! Any help or advice? Thank you.
