Neon Yellow Egg Whites

I hard-boiled some duck eggs and put them in the fridge, like I've done many times in the past. I didn't eat any eggs from this batch until today (two days later). I unpeeled it to find an egg white with several large bright neon yellow spots all around, almost like there had been a leak of Easter dye, only much brighter. The yolk was a little harder than usual, but there wasn't any off smell so I went ahead and ate the egg. So far, no consequences (other than that the egg wasn't as tasty as usual, but that might just be my imagination since I'm worried about the yellow spots). I haven't opened any of the other eggs yet, so I don't know if it was just the one egg or all of them. There was a recent date listed on the container, so they should be fresh. I've bought these eggs before with no problems--did I just get a bad batch?

Does anyone know what might cause bright neon yellow spots on the inside of a hard-boiled egg?

"The yolk of the farm fresh eggs is much thicker and darker in color than the store bought egg. Additionally, the egg white of a farm fresh egg is much clearer than the conventional egg, which has a neon yellow yolk and a translucent yellow egg white. The color and consistency of the yolk and egg are largely due to the chicken???s diet."


"The whites of eggs stored for an extended period under poor conditions, e.g. at unsuitably high temperatures, may become much yellower. Make sure eggs are stored under optimal conditions, and minimise storage time."
