You do not have an undernourished hen. You don't yet even have a hen! She is considered a POL pullet. She may or may not need extra calcium. Pullets that are just coming into lay will drop a few odd balls until their reproductive systems mature.
Don't worry too much about it. Once her system works out the kinks, she should start laying beautiful eggs.
When shell-less eggs happen in an actual hen, then you have a bigger issue.
LOL, good catch!




Yep, they're also known as rooster eggs, too. 
Wait till I tell my daughter who just HAD to have that tiny egg, "you ate a rooster egg!"
