Hello! My four golden buffs just started laying this week. At first, we got only broken eggs with parchment-like shells, but for the past four days or so (I do realize that they will most likely lay a few more strange eggs before they get into a rhythm), the eggs have been pretty normal. Today, one of my hens spend twelve minutes in the nesting box before laying an egg with a rough texture on the bottom (where the egg is brown and what looks like a slightly spotted white coating on the rest. I could always attach a picture if needed. They are fed an organic layer feed and have access to calcium, grit, and fresh water. Any ideas on why this could happen and if it could be a sign of a promblem?
