this is why we candle eggs

I'm in a similar situation with my dud het pied clutch: 4 slugs, 1 healthy egg and 1 that candles yellow, but has a small half cm red spot... Just incubating it and hoping something comes from it - it's been 2 weeks and isn't rotting yet... :please:

Yep, I leave them all in because I have that tiny little glimmer of hope!

I leave them until they go bad. I had many that after 4 or 5 days, start showing veins. I also started marking the ones that show no veins or very little. so far when I get a hatchling that dies right before they pip or after pipping. usually from one of the eggs I marked being with the weak veins. I just started watching for this and will be documenting this for awhile. so I'm not making any kind of statement, just sometime I'm watching.

I don't candle at all, if it looks good it goes in the incubator. If an egg isn't fertile I can always toss it later.

Never candled an egg in my life - Never cut a 'good' egg either

What will be, will be
