This is why most people candle during the first 20 days or so, so that you know when you get to this point what to expect.

Obviously not everyone has candling tools, so no issue there. You really don't have a firm date when she started sitting and 14 eggs is an incredible amount for one hen to handle (which is why she probably threw some out). She knows which one is viable (that's nature!) or she knew she couldn't handle that many. SO *if* any were viable, it is likely the 7 she has left. I would absolutely give it until the weekend given your loose timeframe. Comes this weekend if you don't hear any peeps or see any pips... then likely you have unviable eggs. Good luck!
