I am looking for some higher-quality white eggs. As a kid, we used to blow out raw eggs to dye for pysanky- Ukrainian dyed Easter eggs. Most of the eggs I buy now are brown, and I tried blowing out some super market white ones and they are so thin and fragile that I couldn't do it. Meanwhile, I have beautiful eggs from 25 years ago that have survived. Are they making eggs thinner these days? Anyone have a lead on some uniformly-colored and thick-shelled white eggs?
