Be careful in selecting future generations as his brass will be in the majority of next generation. It will take careful selection and a lot of birds to work that out. If you can locate another cock, even a black Australorp you may be better off. I'm a huge fan of Blue varieties and brassiness is a problem to watch for. The other problem with Blue is making sure not to breed out the lacing. It usually only shows in the blue birds, if well laced will show in splash. Care has to be taken to not use non laced birds or you can breed out the lace all together in your flock. By always using a blue bird, with lacing, in matings you can guarantee it's succession in your flock. Good luck in your venture.
Thanks for the advice! I will take it into my future consideration. This is a learning experience for me. I joined this thread so that I could learn and try to do right with this breed.
