I have a BCM hen that lays an egg with the heavy bloom I never thought about it, but it does look purple. I’ll have to post a picture when she lays another oneBreeding for extra bloom(Egg Cuticle layer) can be done, I've seen what it looks like purple eggs or plum eggs but it's a heavy layer of bloom on top of the brown layer, the Cuticle works as an antibacterial layer
