Why would brown just be on the outside of the shell?
Well that is how it is. Brown is basically from blood somehow. So blood stained on the outside.

Why would brown just be on the outside of the shell?
Reading up on egg shell color & genetics behind it is very interesting. Here is an excerpt answering my question as well:
"Ameraucana birds have the pigment oocyanin deposited on the egg as it travels through the oviduct. This pigment permeates the egg shell resulting in the interior and exterior of the egg being the same blue color. Chickens that lay brown tinted eggs deposit the pigment protoporphyrin on the eggs late in the process of forming the shell. The pigment therefore does not penetrate the interior of the egg, but tints only the surface of the egg, which is why brown eggs are white on the interior"

Eggs only come in 2 colors.... White and Blue. All brown painted eggs are white eggs. The magic of this is how we can make olive eggers.
The brown really should not be there with Ameraucanas.
Quote: I guess you can breed away from it but it is hard. I would only hatch from the bluest eggs to improve egg color.
Mine come from P Smith too. One lays a nice light blue and the other is greenish.My LF Lavender Ameraucana from Paul Smith lays a blue egg with no green tint to it. She laid a LOT of eggs through the winter--usually five eggs a week--and most of the color has been depleted. She has a very, very pale blue egg now with no green.
Yes lol. Those first eggs are awesome. You wait so long its such a treat when they come
My wheaten lay a very nice blue tooMine are as good as my Wheaten Ams.
