Okay so I have candles some eggs that I knew should have hatched around the 15th. I had written the date they were laid on each egg so I could keep track. When these eggs were laid it was cold and windy and the hen didn't sit on them all day but only at night and a little durning the day. My other hen went broody a week later and has sat on them ever since. I just opened one of the eggs and what seemed to me was the chick had another week to go until hatch time. Is this normal? Has anyone experienced this? I can't hear them chirp but when I candle them they are moving.
