Hi everyone. Looking for some advice please. I have 3 Campbell eggs in the incubator. I'm on day 27, going onto day 28 in 4hrs time. Egg 1 has rippling movement around the very edge of the air cell, egg 2 has large shadowing movement in the actual air cell and egg 3 has what I think is a beak/bill, in the air cell very close to the outside shell. How do I know if egg 2 has internally pipped? I'm concerned that there isn't a clear beak shape in the air cell....is this because he just hasn't pipped yet or could it be because he's in the wrong position? Also, from what I've read, I should be able to hear a faint clicking sound or possibly some cheeping from egg 3 will the clear shape in the air cell, but I don't hear anything, although there's plenty of movement. Is there always noise, or are they sometimes quiet? Also, none of the eggs have rock n rolled, or moved at all.... There is clear movement in the eggs though? Sorry if I sound paranoid, I'm a first time duck hatching mummy. Thanks.
