Hello there! As you can see, I don't own any poultry yet as I'm working through the permits, space and everything, but I'm just wondering two things about homozygous ear tufts for Araucanas. What makes the gene lethal? Does it somehow affect organs? Why do the chicks mostly die if they have the EtEt combination? What kills them? Oh, and: Is it possible to hatch an EtEt individual?
