I am not sure of the sex of some of my 3-4 month old cuckoo Marans Bantams. I have 4 cuckoos, 2 black, and 1 black copper. I know for sure one cuckoo is a roo. He crows and looks like a roo. nice hackles and saddle feathers. the others I am not sure on. They are dark like pullets, and have no visible hackles or saddle feathers?? they are 1 month younger than the sure roo. You can tell which one is the sure roo in the photos (he's the tall guy in the first photo!) Anyways, I was thinking I have 2 cuckoo roos (one big one and the one little one), 2 cuckoo pullets, and pretty sure all 3 black/copper are pullets. Not 100% sure on the cuckoos though so I really would like some input. Photo #10 is the closest, colorwise to actual life for the "pullets" in question. photo 4 is pretty accurate too. My flash is just super super bright on my camera! 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. Please judge my birds!!!
