This avian breed represents a specific variety known for its distinctive coloration, substantial size, and primary use as a dual-purpose fowl. The birds exhibit a slate-blue plumage, which gives them their characteristic name, and reach significant weights, making them suitable for both meat and egg production. For instance, a mature female can weigh upwards of eight pounds and produce a respectable number of large, brown eggs annually.
The breed’s value stems from its ability to efficiently convert feed into both animal protein and a consistent supply of eggs. Historically, such breeds were favored by homesteaders and small-scale farmers seeking self-sufficiency. Their robust nature and adaptability to various climates further contributed to their appeal. Moreover, the unique aesthetic qualities associated with their plumage have led to their inclusion in exhibition and heritage poultry programs.
