why have i found two cracked duck eggs near my pool?

  some times ducks swim in my pool and one day i found a cracked egg next to the pool. the next day i found another one. do u think the mother is just rejecting these eggs because theyre cracked, or do u think it was an accident . what else could be an explanation
try to see if the eggs have duckling in them.
Probably because a duck layed them there. I was a lifeguard for two years and I'd have ducks come land in the pool every now and then.
Yes it may of been an accident and then she abandoned them.
