i have a good sized young splash cockerel with what looks like cuckoo in his hackles and saddle feathers, but the splash markings on his larger feathers are not barred/cuckoo. I am not sure if he is a splash cuckoo or a splash with trashy markings, but anyhow, I also have a gorgeous, large splash pullet, an equally large and gorgeous blue, two smaller blues and two smallish blacks in with him. All are this year's birds. Only one of the blacks has started laying, a nice dark (not amazing, but plenty dark) egg.
Keep track of me and bug me in a few months. I should have something hatched that will tell me what I have for a roo. I do not expect very dark eggs from the blues and splashes, just cuz. I bought these birds from someone who bought from all over the country, Bev's, Gabbard Farms, Valentine, and bayhorsebonne, and any and everyone she could find. Somehow, due to family health problems she got busy and lost track of who was who and everything got dumped together. I went down there and picked blind, didn't know what from shinola, but I chose the best I knew how, having just got my first chickens this spring too. Three of the birds I left behind were blue cuckoo feather legged cockerels... (sorry!)
