Let me guess: first autumn with chickens?
daylight hours have dropped, so they have stopped laying and have likely started to moult (annual change of feathers)
Get a light with a timer, set it up so that they get a total of 14 hours of daylight (better to set it up to run in the morning so they roost naturally in the evening).
If you set up lights it will still take 2 - 4 weeks to get them laying again.
If you don't set up a light, you'll get a few eggs starting near Christmas and they'll hit full stride by March.
temperature does not affect laying, daylight does
