I have a free range flock that consists of EE's, Barred Rocks, and a Blue Andalusian rooster. (There are also EE and Barred Rock roosters) I hatched some eggs from them on Tues and was surprised to see 2 blue chicks in my incubator. One of them has a pea comb, so I assuming that he/she is an EE. This chick has a single comb though. Can I safely assume that it is a Barred Rock/Andalusian? What can I expect it to look like when it feathers out?
