Out of my three Olive eggers only 1 laid olive green eggs. The other 2 laid light brown. Well at least one got the gene! I am not sure about the leg difference. Don't remember a difference. I'll go and check.Have they layed olive eggs? I have 4 that are 5 weeks old and only one has the green legs like an Ameracauna while the other 3 look more like the cuckoo Marans side. I didn't know if that might be an indicator of egg color.
