I'm half way through day 18 and approaching lockdown. I candled the eggs this morning as the incubator was running at 37.8 (due to the heatwave - I can't keep the temperature down in the house) so I've turned the inc. temp down and it's back to 37.5 and wanted to see if any eggs were affected. All look Ok apart from one. Unfortunately it's a dark marans egg so can't see a whole lot anyway. It looks a little lighter inside than the others - maybe - so hard to see anything. It's also not an ideal shape it's long and thin. Air sac looks oK. It smells OK too, but this is only my third go at hatching eggs so don't know if I'd be able to smell it going bad through the shell? What do i do - remove it or keep it in for lockdown? Would appreciate some wise words from you experienced folks out there! The thought of exploding eggs is stressing me out.
