There is absolutely no water touching the eggs.

The veins in the discolored eggs are as you suggest, not well defined, and blurry...

I hope it's just my bad luck (nothing seems to be going right for me lately...) and not something I did wrong.

We had the eggs in the tub within 3-5 hours of her laying them, so I don't think, based on replies, that it's the rotating egg thing.

We have absolutely no water in contact with them, so I don't think it's that. Condensate is not forming on them, either.

We didn't use sterile gloves to handle the eggs...I haven't read anywhere that it would be necessary. Is it a possible contaminated environment/touched eggs with dirty hands/dirty tub/bad air/etc?

We have our next clutch due to be laid in 8-12 days. I don't want to have been the cause of eggs going bad, and possibly causing it again. I sure feel incompetent at this point.

How much swing in temp is allowable in the incubator without causing problems? It seems nobody has a real answer for this...I know we want it to be as little as possible, but is a 6 degree swing still tolerable/ok?
