Hey, I have to give credit to my Welsh Terrier (Buster) he alerted me to something going on with Simone...once I addressed it & got her a laying bin, he was not frantically acting to her & her habitat.
So I guess he is the midwife...
I would say anythings possible, you wont be able to tell 100% until several weeks from now, either they will start to collapse (not fertile) or you will start to see veins. Typically a egg that is not fertile is yellowish in color as a fertile egg tends to be white, but its hard when they are first laid. I wouldn't go as far as to get a incubator, but try to house them with proper care and see what happens. Anything is possible .................or as i was saying, 36 eggs, about 10 eggs per omelet, thats 3 omelets and maybe a breakfast sandwich worth. oh ya
