I just had to let you all know that I still have hope. The second little darling laid her first bluish egg today. Although not olive colored like I had hoped, At least it wasn't brown like the first darling. I still have five more that could give olive eggs.
The two that have given eggs so far look identical except their shanks, one has greenish/tan and the other has bluish/grey. They both have pea comb and fluffy chin and cheeks. Out of the 7 pullets that hatched these two are the only ones with fluffy faces.
