My Americana has always laid greenish eggs. This year no green eggs. I thought maybe she quit laying, but for a few days in a row I have found her in the nesting box followed by a pinkish eggs. None of my other girls (5) lay pinkish eggs, all brown. Is this possible?
I've never had that happen with my EE's but my cuckoo maran was laying light brown eggs when I got her, much to my disappointment, but after she went broody, the eggs darkened up quite a bit. Interesting to see if anybody else had this happen!
I understand that the blue egg colour does get paler over time as the laying cycle progresses and that eggs that start with nice colour will end almost white (then the colour saturation comes back when the new laying cycle starts after moulting). A green egg is a blue eggshell with a brown tint over top, so my guess is that your girl has depleted her blue pigment and all you are seeing now is the pale brown tint on the egg. See what happens in her next laying cycle...
