The "Ask Anything" to Nicalandia Thread

[nicalandia]

I am new to breeding/genetics but find it really fascinating. I recently purchased bbs pure ameraucana eggs from a local breeder. They are due to hatch tomorrow. This week she found out some concerning news. Her blue ameraucana roo, who always produced pea comb SOP babies with other ameraucana pure hens, sadly made all babies with straight combs when that same roo was mated to a maran hen for olive eggers. This was the first time she bred outside of using her ameraucana hens. My questions are: is this concerning and does this make that said blue ameraucana roo not a pure bred? Should I not use the babies from this blue roo mated with the pure ameraucana hens for my ameraucana breeding project?

Is he the Only Rooster with those hens? If he is the only one(no chance of another roo mating with the Marans) then that confirms that he is indeed P/p+. Also the chance of those Ameraucana/Maran cross hens laying Olive eggs are slim to none since the Blue egg gene is linked to the Pea comb with a 2-4% chance of crossing over(Oocyan mutation crossing to the p+ single comb mutation)...

If we assume that he is P/p+ then that means that at any point of his ancestry there was a cross made to another breed(not unheard of), most likely to introduce a desirable trait...

If the Ameraucana LOOKS like he has a pea comb, it should be impossible (genetically speaking) to get a large number of chicks that ALL have single combs. Worst case, it should only happen in half of his chicks with a single-comb hen.

If it's less than 50 chicks then a single clutch can still produce all single combs..

So in your opinion (if the said olive egger babies are indeed his, therefore making him a P/p+), would the babies I have hatching today from that same rooster mated to a pure ameraucana hen (P/P) be viable for the ameraucana breeding program or would this make them too risky to be using?

Also, thank you so much for your knowledge and insight. It was extremely helpful and insightful. I appreciate you.

What does a ayam cemani x laghorn look like? I really curious

Yeah, only the P/P ones, P/P males(specially) have tight combs. the P/p+ males have larger and sometime floppy pea combs.


Ameraucana roosters P/P should have tight small combs with nearly absent wattles.

P/p+ males have larger combs with medium sized wattles.

That will depend on the color of the Leghorn. If you cross a Cemani Rooster with a light brown leghorn. All of the chicks will hatch with black feathers, the females will look nearly adentical to Cemani(black skin, black feathers), the males should hatch with lighter skin and some leakage on the black feathers.

It's a bit exaggerated and can be a bit smaller in some birds, but here's a bird I have that is P/p+. Just for a bit of reference

That male is clearly an F1 of sorts. The issue becomes more complicated when you take the F1 and keep breeding back to pure pea comb, in that case the P/p+ males(F1 back to Ameraucana) have smaller Combs than the F1s, but not as tight as the pure ones.

This is the rooster in question that confirms that P/p+ males that have been breed for generations can have small Combs.

Before assuming anything, I would test breed him with a single comb hens. Let them be without a rooster for a few weeks, then put them with him and hatch at least a dozen eggs

Thank you! I’m so glad you saw the picture from the forum. I was going to reference it here. That helped a lot. I know the breeder said she was going to test him for the homozygous blue gene testing the featherIQ company now has, and I will mention to her about testing with other single comb hens. She is really nice and also is learning and into genetics, so she will appreciate all this too!
