I have 2 girls, a buff Orp and a black Cochin. Both are now laying. My buff's eggs are a pale tan and slightly rounded. My cochin, who just started laying in the last couple weeks, lays a darker egg that's slightly pointy on one end. This morning I went out there to find an egg that looks like a mix between the two and it's VERY darkly speckled. Are either of these breeds known for this?
