Can anyone tell me if they think this might be a guinea egg. I have 6 old hens who lay regularly and our guineas are with them. Guineas are about 7 months old and I think this might be one of the first eggs from our 3 female guineas. Apparently 2 eggs were laid but one had a shell so think that it was broke and laying just outside the nest. This one is intact. About a week ago I got 2 mis-shapened with no shell just a rubbery kind of outside. The egg on the right is kind of a lite tanish color and our hens don't lay that color. We do have ameracanas but they lay the green eggs. Could this be my guineas starting to lay?
