Today is the shortest day of the year. Short days detected by the pineal gland signal animals to curtail reproduction.
At my latitude, day length was 1 second shorter than yesterday and 3 seconds shorter than tomorrow, January 1 will be 39 seconds longer than the day before. By the end of January, each day will be 45 minutes longer than today. Light period will be 2 minutes longer per day than dark period. Hens at laying age but not producing may start in February. Daily change is greatest the third week of March.
Eggs are soon in your future.
