The "Ask Anything" to Nicalandia Thread

Looks like my AustraWhite in coloring.

In my case I fully expect rumpless birds like this pullet, but without beard and more black specks.

The rumpless gene is Semi Lethal, so, how are you gonna compensate for the lower hatch rate?

This is the first time I hear that the Rumpless gene is semi lethal. The Tuffs are(Lacking in the rooster in question).

IIRC, birds blood vessels are right next to each other so that the warm arterial blood going out warms the cool venous blood as it returns -- very efficient.

Indeed! In doing so, they both reduce the amount of cooling of their core that having to re-heat that blood would cause, and the amount of heat lost to the environment through their shanks. Birds are remarkably efficient in so many ways.

This is a common misconception, but it is indeed the tuft gene that's lethal, not the rumpless gene. It's believed that rumplessness can cause a loss of fertility due to males having a more difficult time breeding when rumpless, which is why some Araucana breeders keep tailed males and thus produce some tailed individuals from their flocks, but there is no lethal mechanism with rumplessness that I've ever encountered.

I think it's a dominant trait over tailed birds with lower fertility (so still potentially a low hatch rate). But even breeding rumpless to rumpless can lead to tailed chicks according to where I got mine from

I don't know what the dominance is of the gene if I'm being honest, only what I've read about struggles with fertility in some flocks and that being the reason to keep tailed fowl in the mix.

I guess I'll find out in the spring. Out of the 4 males and 5 females I have, I'd suspect at least a pair to be heterozygous and produce tails if it's how I think it is.

The improved hatch rate doesn't seem like it's worth it to the place I got mine from, they cull tailed ones at hatch before selling, so it wouldn't be worth hatching more eggs if those extras had tails I would think.

So what you are saying is that.... You have and breed Araucanas? Care to show pictures of their eggs?

Mine didn't decide to lay this year as pullets before the snows came. I can get pics of the 10 I'm keeping if you'd like (2 tufted males, 2 clean males, 2 tufted females, 3 clean females and 1 tufted male back up), and link the image their breeder has of the eggs, but I unfortunately didn't get any eggs this year to even look at
