seriously?...it may take a young hen, especially those without a leader, a little time to figure out what to do... they are orphans you know and maybe the breed is geared more foe production than instinct. I had one that was confused when starting to lay and i just put her in the nesting box with reassurance. You might try rearranging things a bit to help her out.,even placing her in the box with the egg after the fact.
