As luck would have it,the last 3 peachicks I hatched last year included a pair of Opal B/S,,,IT does take a lot longer for this color to be distinguished sex wise as the opal color comes in very slowly but once it starts the male gets laced feathers behind their necks.I will be adding a plain Opal and a Opal pied hen in with Opie this spring,and I may add a BSSP hen so we could have some interesting Opals this summer.
