How many days,on average, does a female Yorkie in heat release ovum? With multiple breedings/ties: If it is possible for some of the eggs to be fertilized on the first day and some to be fertilized on the last day of the eggs being released, won't some of the puppies be premature if born 63 days from the first tie?
