My cochin has been sitting on 5 eggs since the 5th of this month. Early this evening I went to check on her and found and egg had been kicked out of the nest. I picked it up and put it back under her. The egg wasn't there this morning so I am guessing it may have been out at least half the day. If the egg was fertile and developing..would it still be? I understand it take 21 days to hatch and it may not have been fertile to start with. But was still curious.
