Japanese Bantam
Gallus gallus domesticus
✨ Fun Fact
The short-leg gene in Japanese Bantams is lethal when inherited from both parents — eggs with two copies of the gene never hatch. This means every nest of Japanese Bantam eggs contains approximately 25% unfertilised-appearing eggs that are actually non-viable homozygous embryos, a fact known to Japanese breeders for centuries.
An ancient true bantam that has been kept in Japan for over 350 years, featuring a uniquely short-legged, upright-tailed silhouette unlike any other bantam. The tail of the Japanese Bantam is carried nearly vertically — touching or almost touching the back of the head — giving it a distinctive 'letter J' profile. Short legs are caused by a gene that is lethal in homozygous form, meaning every breeding produces approximately one third of chicks that do not survive — a genetic characteristic unique to this breed.
