Araucana
Gallus gallus domesticus
✨ Dato Curioso
The blue egg gene in Araucanas is caused by an ancient retrovirus insertion — the virus essentially 'hacked' the genome of ancestral South American chickens and the mutation was passed down for generations.
A fascinating South American breed originating from the Araucanía region of Chile, famous worldwide for laying blue-shelled eggs — a trait caused by a retrovirus that inserted into the genome thousands of years ago and became heritable. True Araucanas are rumpless (no tail) and have distinctive ear tufts rather than a beard, setting them apart from the similar Ameraucana. Their blue eggs contain the same pigment (oocyanin) throughout the shell, not just on the surface.
