I agree. The earlobes on a Cream Legbar are supposed to be white and this cockerel not showing very much white on his ear lobes. This cockerel (and his brothers that were culled) also are single barred which means that their father was a non-barred bird and therefor NOT a cream Legbar.
Note: The way the auto-sexing breeds work is that males, who carry two complete chromosomes, carry the barring gene on both Chromosomes, one barring gene from the sire and one barring gene from the dame. The females have one full chromosome and on sex-linked chromosome. The full chromosome that they inherited from the Father has the barring gene, but the sex-linked Chromosome from the mother does not have space for all the genes that are on the full chromosome and don't carry any of the sex-linked genes. So not barring gene it inherited from the mother. Pure breed Pullets therefore only have one barring gene and pure bred cockerels carry two barring genes. The double dosage of barring creates twice as much diluting in the cockerels as in the pullets which is why the cockerels have a large white patch on their head and a lighter color with blurred stripes, while the pullet has a small to no visible white dot, darker down color and clear stripes.
This cockerel is too dark to be carrying two barring gens. Birds with two barring gene have a grey body color and black and white stripes on their tail feathers. This cockerels has a black body color and black and grey striping on his tail.
No, he is NOT cream either. If he was Cream his hackle and saddle feathers would be yellow and the triangle on the end of his wings would be white rather than brown.
