I have another post with pics a few posts down, but had another question. Do Black Copper Marans get combs fast whether they are roos OR hens? Thanks. MIne are 3 weeks old, and some are developing combs faster than other kinds of birds.
I was able to determine the gender of my BCMs after only 5 days. The cockerels had darker reddish combs. Combs were getting bigger really fast compared to the pullets combs.
