You get them in the winter from megafarms (like the one that burned) who spend big bucks to keep the lights on most of the night in the winter so the chickens continue to lay (egg laying is triggered by day length). This practice can shorten their laying life, which is no big deal to the conglomerates - just butcher them after a year or two of laying and replace them with younger birds. In my chicken yard, laying slows way down in the fall and winter and picks back up in the spring and summer - unless I supplement with artificial light. (I'm unvaxxed and based, BTW.)
