Long time no talk forum. Pearl, Daisy and Shadow are doing great. Theres a new addition to the crew and her name is Maggie ( shes a magpie ) Anyways, my question is....when can male ducks fertilize the eggs? See the thing is Pearl has never sit on eggs before, she would always break them and eat them. About a week and a half ago she built a nest and is sitting and guarding 18 eggs....she is very very noisy and cranky when anyone or anything gets close to the their cage....and when i say noisy and cranky i mean like very bad...she get all puffed up and ill......iv never seen this before cuz i hatched pearl daisy and shadow from incubation and raised them...just wanting some knowledge about all this breeding stuff.....funny thing is shes sitting on hers and daisy's eggs. Just wondering if instinct is telling her they are fertile.
