Ok this is our first clutch and it's about day 27 and all the eggs look great! No spots, all nice and smooth and going along nicely. Well the other day I noticed one of the eggs dimpled on the top in the middle, but after opening the container and passing some air over the egg the dimple popped right back up and the egg was back to normal. I lowered the temp in the incubator from 88-89 to about 86-87 to see if it made a difference but nope it keeps dimpling in that one spot but when I pass air over it, it'll pop back up every time. Humidity hasn't changed at all since day one...should I just leave it be and just make sure it doesn't get worse or it this totally normal? There are 9 eggs and this is the only egg that's doing this dimple trick. Thanks for the help!
