Hello, my welsh harlequin duck started sitting on the eggs so I let her gather a clutch and go broody. Shes sat on the eggs all day long for 2 days. But I noticed that the other ducks are pushing her out at night and laying in the nest. And last night they busted one of the eggs. This morning I grabbed the busted egg and surrounding bedding and tossed it. Some eggs have dried yolk on them. Will they be ok to leave in there? I put an x on the first 15 eggs. So I knew this morning that 3 had been laid in there and which ones they were. Should I close in the area around the nesting box so she is left alone? Any advice is welcome as this is my first time letting a duck set a nest.
