Ok so as far as breeding them in the future should I only keep the rumpless?
I read this from the club site: Araucanas are rumpless, which means that they do not have a tail, any remnant of a tail, or even an oil gland. This trait is caused by an autosomal dominant, non-lethal gene. Even though the gene is non-lethal, it can have an affect on fertility because the lack of movable tails can create difficulty in maintaining the physical contact necessary for fertilization. Some breeders trim the fluff around the vent to aid physical contact. But other breeders have found that if they dont trim and let nature take its course, over time the fertility will increase. Other breeders make the mistake of mating a rumpless bird to a tailed bird in an effort to enhance fertility. If the rumpless bird is herterozygous (one copy of the rumpless gene), the resultant chicks will be 50% rumpless and 50% tailed. However, many of these rumpless chicks will only be partly rumpless with a few tail feathers at odd angles, creating an ugly bird. This is because rumpless modifier genes exist, and breeding to a tailed bird introduces these genes into the offspring. By breeding only homozygous rumpless to homozygous rumpless, over time these modifier genes get eliminated.
So I am guessing I only want to keep the rumpless and cull the others right?
