I agree,I think there is a problem with the down color on all three of those chicks. The Wheaten is obvious to see, of course, when very young. The other two mask show a slight V pattern on the top of the head and again the line through the eye shows a definite e+ on the Yellow banded chick and the black banded chick. For the proper lacing as adults they should not show any of these patterns as chicks. That being said, I understand that in some countries (Australia for example) it is nearly impossible to get Barnevelder chicks that do not have Ewh or e+ patterning. In those places (where import restrictions make getting pure bloodlines nearly impossible) one should cull for those color traits in chicks to get closer to the Eb chick down pattern. I have hatched dozens and dozens of Barnevelder chicks and not once seen either of those patterns in my day olds. When I mentioned being able to sex them at day old from the down I meant lines like what I have, not those influenced by Ewh or e+ genetics.
Hope that helps,

the e+ or eb/e+ pullets can be seen in the USA too(as eb/e+ or e+/e+ males should look identical to eb/eb males when adults, so one sees more e+/eb or e+/e+ females)
