I truly truly believe that for the first week I take the crumbles and grind them smaller. I've had some hatches where the I would watch chicks pick them up and put them down. I've also had 2 hatches that 1 died on day 7 before I realized the problem, and a hatch of 7 that were flinging food all over and not really swallowing. After I grinded it up, they were vultures! I always do it now. I think crumbles are manufactured for average sized birds like Orps. But with smaller breeds, they don't sell smaller crumbles.
