I have 6 chickens that are nine weeks old. They were labeled as barnyard mix. I believe the black ones are either black Australorpes or black copper Maran‘s from what the sellers own. I’m thinking the two smaller ones are australorps and the two larger ones are marans? The larger ones have bigger combs, but they are very pink compared to my rooster especially for 9 weeks. They are also started to get brown feathers on the neck area. Does anyone have experience with young hens and large combs?
