What causes brown eggs, to be brown inside?

Most Brown eggs are also brown inside(lighter) due to protoporphyrin. Most people think that they are bone white inside, most membranes are white some are translucent. Then white ones when dried will make the inside of the shell look white but when removed it will reveal a lighter brown.

The location of protoporphyrin in the eggshell of brown-shelled eggs.

"The majority of the protoporphyrin pigment was located in the calcareous part of the eggshell (80-87%) with a minority contained within the cuticle (13-20%). These findings suggest that studies focused on maintenance of shell color in brown-shelled eggs need to consider the stage of egg formation at which the reduction in pigment deposition is occurring"

Interesting, cuz I get more with a white/Whitish interior rather than the brown I found.

Yes, it will vary from one egg to the next one. Depending on the hen and breed. Yours happen to deposit more brown inside than others, which like many traits it can be bred for. I once had that idea to find hens that laid the darkest brown inside and breed it to blue to produce true green eggers, just not outside. Perhaps its yet another of the many possible breeding projects that seem to just appear to you from your mysterious and amazing coop.

True Green Eggers, sound like they'd be interesting.

The egg was from the coop that's not very mysterious. The egg was from one of my 2 Heritage Plymouth Barred Rock Hens.

I was reminded of wanting to update on this guy, quoted above. This was him at around the time I last posted him, early December at 6 months old:

This was him at the beginning of January at 7 months old, the most recent picture I have of him at the moment:

If this is heterozygous mottling, will he molt the white out as he ages or does it sometimes remain despite being a recessive gene? He's not getting big blotches like the previously mentioned color-changing birds, just an increasing sprinkling of spots here and there, especially on his hips and butt and under his wings.

Small spots is how mine start out, just gradually increases during their molt.

Interesting, so he's kind of following the same pattern after all, then.

This is his hatchmate, for the record. I assume they're at least half siblings with the same father but cannot confirm as I bought the eggs they hatched from from another farm. Not a speck of white in sight on her.

Yes, though not starting head, or face first.

Have you checked her under fluff?

 

[pipdzipdnreadytogo]

I've checked her vent because I suspected she might have laid an egg yesterday and didn't see any white in that area, but I haven't looked anywhere else on her. She's pretty chill so it shouldn't be hard to look her over tomorrow if I remember to.
