Kind of a dumb question, but I found an egg today (the second ever for my hens!) which looks white compared to a normal brown egg, but ever so slightly brownish (pinkish?) when set against my white counter-top. My hens include a lakenvelder, andalusian, faverolle, EE, jersey giant, and a mixed breed something or other who looks to have some rosecomb bantam in her. Any thoughts?
