I have a saddleback Sebastopol goose and her daughter that have eggs that are hard to see into when candling because it appears that they have pigment in the shell that makes it look reddish when you candle the eggs or they must be super thick shelled. Frequently they don't dry down enough and I lose the goslings toward the end of incubation. I've come to the conclusion that I may need to cool the eggs longer than recommended to see if that helps produce more live hatches. The older goose sometimes has a very slight pinky-beige wash on her eggs but not every time but today I found this BROWN egg in her nest!!! I've had this goose since 2008 and she has never laid a brown egg until today! CRAZY! Has anybody else ever had tinted or brown Sebastopol eggs?
