Try giving them things like wheat, yogurt, oats etc. The yogurt gives them more calcium and the wheat &oats will keep them warmer since they have something moving through their tummies. Are you feeding them melon of any sort? If you are, STOP! They may like it, but it also rapidly slows egg production. Make sure they also have plenty of fresh water! They won't drink dirty (at least mine don't). If they are stressed, this is another thing that slows production!
Hope that helped!
Good Luck! p.s. what breeds? Some are better layers then others.
