I tried taking a picture, but my camera refused to put the egg in focus, so I'll have to describe it. I have one EE who lays blue eggs and the past three have all been odd. The shell is really thin, with an uneven texture (reminds me of when they spray mud to texture walls--both in roughness and because it has the same kind of mat finish--like flat paint instead of the slight sheen eggs usually have. She has equal access to food/water/oyster shell as the rest of the hens, and I'm not sure which of my EE it is--I have three and I'm almost never around when they lay. Any ideas about what might be causing the problem?
