Weird blue splotches on some eggs

[Books and Chickens]

Hi! Anyone ever seen this before? Because I sure haven’t.

Three eggs in the nest had blue splotches on them. Washable blue splotches. I’ve checked the run, and there’s nothing my girls could have gotten into that would explain why they’re wiping blue stuff on their eggs. Could they have come out this way? And is it normal?

For context, I just got back from a five day trip and a certain someone was SUPPOSED to gather the eggs, but failed. So it’s quite possible that the three splotched eggs came from the same hen.

What the heck is this stuff?

I think the hen laid the egg fine, then the egg got something on it from the nest or some chicken's butt feathers.

Here's an article on egg quality I even looked through just in case there is some rare ones like that, and found nothing even close.

This part looks like it was something runny and wet on it.

What breed are your hens?

Have they gotten any berries or red cabbage lately? Looks to be post lay coloration.

When the egg is laid, it's still a little wet. If the hen has some dark berry residue on her but, it may have mixed with the moisture on the egg.

I have two White Leghorns, one Salmon Favorelle, some Rhode Island’s, a few Color Packs, two blue eggers of a breed I can’t recall, and a few others of uncertain origins.

I wondered at first if the blue color of the blue eggers just didn’t distribute properly (if that’s even how it works), but then it started washing off and I was further confused.

They do have blackberries in their yard. I suppose that could have been it.

They have access to a few blackberries. That could definitely have been it!

Blackberries then. Weird chicken. What’s she doing sitting on blackberries??

It's likely from droppings
