Detailed profile of this breed: origin, year of creation, recognised varieties and official approvals.
Breed summary
I cannot find authoritative documentation for a rabbit breed formally named "Gris fer de Vienne" in the sources available to me (cutoff June 2024). It may be a local or historical name, a color variety of a better-known breed, or a breeder's strain rather than a standardized breed. Because this name is not confirmed in breed registries or major breed standards, I cannot provide reliable quantitative measures (weight ranges, ear length, litter size averages) or definitive statements about official acceptance.
Detailed origin
There is no verifiable, citable origin history for a breed under this exact name in the reference materials I can access. If the name refers to a regional variety from the Vienne area (France) or to a color derived from the Vienna/Germanic lines, its origin would likely be local breeders selecting for a particular iron‑grey coat. To produce a valid origin account I need a primary source: a club/studbook entry, historical reference, or breeder documentation. Without that, any precise timeline, founding stock, or development process would be speculative.
Detailed description
Because the breed name is not documented in recognized standards I cannot safely give specific morphological or production data (weight, body type, fur density, genetic color mechanism, temperament scores, reproductive parameters). Qualitatively, if this is a named colour variant (“iron grey”) it would concern coat pigmentation and pattern; quantitatively those traits are described in standards with exact color codes and acceptable faults—data I do not have for this name. Please confirm the exact name (alternative spellings), provide a photo or a link to a source (breed club, studbook, show standard) and I will compile a full qualitative and quantitative profile from verified references.
