Only one chicken not laying

There is no rhyme or reason how long of a winter break a hen will take. They are all individuals. Even though winter solstice is December 21, days in the middle of January aren't really that much longer.
Where are you located? Here we are a full month later and at my latitude, days are only 28 minutes longer than at solstice. But from here on out, the increase will be speeding up every day.

I am in southeast texas.
