They sure did, Andy.
Last time I got chicks (around the same time) I started getting eggs in November and they laid all through winter without artificial lighting. That was a few weeks late if I recall. Generally you start looking at six months of age.
I remember checking the nestbox, checking the nestbox everyday, several times each day, as freezing temps were here and I didn't want to lose my first egg to freezing. It was quite the present and surprise to finally see that first little brown egg.
Give us this day our daily bacon.
