Hello all,,, I am new to ducks and they have been doing well... I have a nest full of eggs but I got home last night to a terrible thing... My son let them out to get their daily swim and feed them when he got home from school and when I got home two two females were gone completely and one was laying in yard. Coyotes dont come to property during the day and I found what looks like falcon feathers in the yard. So I have all these eggs and no female to sit on them,. How can I tell if they are viable I was not expecting this so I dont have an incubator.
