I also thought that the back was a bit short for perfection. And the wings seem a little more open. I also think it is a Cream Legbar, and I don't know if the book actually identifies it as such. Long backs in animals are a bit difficult to come by.
Remembering that the standard of perfection is intended as a guide and not a minimum requirements - I think it is a quite nice cockerel actually. Also, a picture is a split second in time...so he may have looked better in real-life wing-wise.
BTW, I saw all 5 of the Cream Legbars that were entered in the Fancy Feathers 4-H Club show in San Marcos, Tx on April 13. I have to say "hats off" to the people who entered their birds. There was a lot of admiration for the cockerels that I overheard from spectators. Of the two cockerels, the one who won was a bit more mellow, larger in size and colored a tad better than the other. But the write ups from the judge were that the one was wild, which I think means that the judge couldn't judge him. The other one got BB (Best of Breed). (I think that there has to be at least two of the breed in the show for one to be considered best)--- So really one small step forward for Cream Legbars - one giant leap for that particular chicken. One can only tell so much from a photo-- I understand now why judges would want to hold the bird. All in all it is fascinating.
Lately, I also encountered a website, where productivity is emphasized.
http://www.utilitypoultry.co.uk/upba.shtml IMO some great insights there. I think in another post - GaryDean26 mentioned that Applegarth was one of the people instrumental in bringing back the CL - but perhaps it is a different Applegarth?
