AN UNBIASED VIEW OF SWAN EGGS FOR SALE NEAR ME

I am no pro on swans. I fairly think that a night-time predator filched the eggs. I have read persons say that their birds( chickens, geese, no matter what) get rid of infertile or nonviable eggs from their nest. In forty years I have not experienced a fowl get rid of their own personal egg/s in the nest aside from unintentionally. luvswans stated
