My chick has no tail!

[HorseGirlAbby]

So, I have eight eight-week-old chicks, that I hatched this spring. Out of the eight, four or five are pullets, and one, Mohawk, doesn't have a tail! They are half-Ameraucana, and Mohawk's mom is Silver-laced Wyandotte. Her full sister has a very nice tail. Is the Araucana gene just very prevalent in this chick? Or is she just growing slower? Here's a picture:

And one of her head, if that makes any difference:

Thanks in advance for any help!

They wouldn't gave Araucana genetics unless they had Araucana in them. Ameraucana and Araucana are different breeds entirely

Well, okay, do you have any idea why she doesn't have a tail, then?

It's likely just a random mutation

 

[HorseGirlAbby]

Ok, so Mohawk has grown a tail now. I guess she was just slow, now I can hardly tell her from her sister!

Ameraucanas were bred from Araucanas and others..so..yes..your bird has some of those genes present, but, is it possible your bird lost its tail feathers, or will grow it, or has it always been this way?
History. The Ameraucana was developed in the United States in the 1970s from Araucana chickens brought from Chile. It was bred to retain the unusual blue-egg gene of the Araucana, but eliminate the tufted and rumpless lethal alleles of the parent breed. ... The name derives from "America" and "Araucana".

Ameraucanas were bred from the Araucana, hence the name. They aren’t entirely unrelated.

I suspect the chick lost its tail feathers, or they haven’t come in yet..

She never lost her tail feathers, she was always that way, until a month ago. She grew all her tail feathers in, and now looks just like a normal chick. I thought they had Araucana genes!

Never mind, I finally see you updated..!

The blue egg gene is an Araucana gene..that’s where they got it from..but they bred out the “rumpless” gene because it was associated with a lethal outcome, and improved the rate of lay..
