I was looking at this site: http://shilala.homestead.com/candling.html The site states this: The egg on the right shows highly defined pores. Eggs that look like this under candling have a slim chance of hatching in my experience. I've noticed that it mostly depends on the severity of the porosity. My broody is sitting on 10 eggs, she's only on day 2 but I candled anyway. All the eggs have pores like the picture on that site. So it got me thinking and experimenting. I've candled about 2 dozen eggs that I've collected for food and ALL of them look like the picture...ALL of them and they come from 23 different hens! Is it possible for eggs to have too many pores and they won't hatch? I'll take a picture and show y'all what I mean.
