I've been candling and I keep ending up with completely dark eggs and it's hard to even see a clear spot. I'm almost sure that when I started they were all able to be seen into. I did notice yesterday that I have a few porous eggs. They are on day 14 and they are getting heavy. Oh and will a slightly higher temperature make them develop faster? At first the temperature was a little low so about day 5 I turned it up and now it's around 102-104 air temp. I'm kind of worried though. I hope out of 12 eggs I get at least 2 babies and then I'd be happy.
