My son showed at the fair this weekend and did well with his Silkie. After he showed, I stuck around to see how others from his school did. Two students showed 5 month old cochin pullets. They are nice birds, great coloration, awesome foot feathering, nice carriage. His comment was that they were not "basketbally" enough. I thought that this was a characteristic that develops as the bird matures. He suggested getting new birds with better form and not using those birds in our program. I asked if the age mattered, he said no, that they would never fill out. So, I thought I would ask all of the cochin experts out there... what age do you use for form? How old do the birds have to be before you can access their "basketballness"?
