They are showing less vascularity than I would expect at 37 days, but they look as though they MIGHT be fertile. At what temperature is your incubator? A lower temp setting might account for the low number of blood vessels after 37 days of incubation.

Also are you careful not to rotate the eggs when you handle them? IE, you should mark the tops of the eggs gently with a penciled "X" and always make sure to keep that "X" on the top when moving or handling the eggs.

Hi sorry it's an error 28 days. Temperature is 30.

We are careful and do not rotate them

Ok, that is more understandable. You could up the temp a bit to 31.0, 31.5, or even 32, although at 32 you might get shell abnormalities. Otherwise just keep them at the temp you have been using and be patient.

Thank you would you say they are looking good?

I think I can see some small blood vessels in the eggs, so, yes, they seem to look fertile at this time.

If you post more pix in a couple of weeks, and more vessels are evident, that should allow for a more definitive answer.

Hi here’s an update of what 2 look like. It has now been 8 weeks and 6 days in incubation. What do you think? Looking good or bad?

Many thanks

Are these the same two eggs that you posted last time? Either way, the eggs pictured today do NOT look fertile. I would still incubate them until you reach 120 days of incubation just to be on the safe side, but I am not seeing anything promising as of today.
