Just a suggestion. It might be easier if you stayed in the same color famly (red) and general body type (dual-purpose). Speckled Sussex is the hardest variety of Sussex to get right because they are a tri-color breed. Smart of you to start with such an august strain as Albritton. Light Borwn Leghorns are e+ wildtype. A challenging color to keep pure. Red Sussex are Speckled Sussex without the speckles. They definitely need help, ultra rare.
Best,

I'm glad you mentioned the Red Sussex. I will add them to my list - there isn't a Sussex I've seen I don't like, honestly. I don't believe I've seen a Red, but now I'll start looking around

I know the Speckled is difficult, but they blend into the landscape well, and Tony has agreed to let me send him pictures as they grow up for help in selecting what to keep and combine.
