I had no idea about the cardiac conditions in the chocolate males. I had three that died the same way and I could never figure out why. They were routinely wormed, treated for cocci, and 100% free of mites. I took the best care of them that I could. They lived indoors. For no reason their combs turned purple and they spent the rest of their lives on scrambled eggs and vitamins. I knew that I should have put them down but I couldn't because I badly wanted them to live and I hoped that they'd pull through. They have always haunted me. Thank you for the peace of mind - there is nothing that could have been done for them. I have always felt so badly about them.Thanks MountainSerama's.
I had bought 2 chocolate Serama cockerels, both frizzled, from a breeder in Texas last winter. They were both without red leakage and had minimal silver in the neck hackles and shoulders but as they matured, they died. It was the cardiac issues that is in this breed. The breeder had contacted me and told me they were dying on her too, just the males and just about breeding age. They would be fine then turn weak, the combs would turn purple and they just died. Nothing to do with being cold, mine and hers were both kept inside in the winter with heat. So, I just had finally gotten down to just the 2 chocolate cockerels and the blue mottled above for males and I have 4 nice chocolate hens and 8 black hens. I had lost the 2 older cocks that were around 5 yrs old late last summer to just old age I think and had hatched several chicks last summer, almost all pullets!
So I've been down to just the above cock and mostly keeping him with the black hens. The black and chocolate hens are not from solid to solid breeding so I still get some mixed colors but have hatched 3 blues that the chick down is more like a solid than mottled pattern. I have a breeder that is going to be saving a black cockerel for me this year. Neither of the chocolate cockerels produced a single chick, infertile. I hope breeders understand how truly difficult the solid colors are to perfect and to breed true. They are not cheap for a reason. At least the blue mottled cock I have now has no red leakage and no pattern to him. "If" all he has is solid color with mottling, mottling isn't too hard to breed out as long as you are careful and don't cross back with others that will carry only 1 gene for it. I need some small breeding pens so I can separate the hens but that isn't done yet
Let me know if you need another black cock. I have some decent ones, they are small and fertile. My biggest issue with them is their white earlobes but they have a good clean start on yellow legs.
