White leghorn stopped laying

[Lin_0330]

Hi,

I have a white leghorn which I bought as POL 2 month ago and she started laying roughly 3 weeks ago.
She has laid almost everyday but this week she only laid one egg on Monday and stopped.
I am not sure what could be the problem?
Does White Leghorn in general lays during the dark season?
Not really cold at 5he moment, around 12-16 degrees during daytime and 5-8 degrees during night.
Daytime 7:15-16:00

Most pullets will lay all their first winter....but not all.
Do you free range?

Where in this world are you located?
Climate, and time of year, is almost always a factor.
