Hello. I'm new I have a great fascination with birds and eggs. I have 8 Pekin Ducks as well as many other mallard ducks. I have about 20 Pekin eggs in my incubator right now. A lot are developing with veins and such, but there are some which have a quarter sized ring with a dot in the middle. Is this a blood ring? If not, are they fertile or should I just toss them? And my Pekin ducks aren't too smart... they tend to lay their eggs in the shallow creek or in the pond[which is just about a foot deep]. Do these eggs have any chance of survival once they've been in the water? My sister found a couple in the creek this morning and brought them in. Needless to say I dated them and put them in the incubator, but I just want to know if I'm wasting time & incubator space. Thanks!
