I'm sorry to hear that.
It needs to be White leghorn to get 'Super(egg production)' in their name.
I only have rooster and from MPC and crossed him with F1 OE, ofspring lays same color as her mother. Wonder how chocolate my roo is...
One parent does not have to be a leghorn to make a "super" chocolate or super blue egg layer. One parent just has tp be a production layer of white eggs. Several breeds fit the bill.
