My female duck daisy has a male freind Donald. She has made a nest and is sitting on some eggs. She wont let anyone near her except for me (I the owner. ( I look after her and she trusts me) ) when I give her food. Donald has recently been sitting near her and protecting her. my question it how do I know if the eggs are definatly fertile and if they are what do I do???? Daisy and I are both new at this so im a bit unsure. So far I have just been leaving it to her. When/if the eggs hatch do I have to take the ducklings away from her or do I let themfollow her around all the time?
