We really have not paid any attention to the eggs available at the grocery store since we got our hens. Today we were shopping and I decided to look at a dozen AA white eggs. They looked like they were spray painted with white paint. We also noticed some imperfections - such as raised areas on the shells that looked like they were sprayed over with white paint. Is it possible that this is what we were purchasing in the past and just didn't know any better? Our eggs from our girls seem SOOOOOO much better than what we saw in the grocer's fridge.
