Fertilised Leghorn shop bought eggs?

[Pollmadoll]

I have just put some fertilised blue shell leghorn eggs into my incubator and can see an air cell forming .?

They're probably not leghorns, since leghorns don't lay blue eggs Could be leghorn hybrids, though.

All eggs will have air cells. What you want to look for is development of an embryo, which you can start to see between 3 to 5 days after you start incubating the egg.

I meant cream legbar.

It is a Royal legbar

Does anyone know if a detatched aircell changes shape during incubation ?
