Australorps breed Thread

I do understand that blue/black/splash are all part of the same gene theme.
So, the black spots on a dominant white x black crossing actually don't look the same then? Cool. Thanks for the clarification. And from what y'all are saying it is very likely that the little Dalmatian chicks I got from my friend are indeed a cross from her black Australorp and half buff Orpington. Thanks!

Yes!

It is not blue genetics and will not breed like the chart.

They will be nice chickens though. You will love them!
 
My Black Austrolorp rooster and Red Sex link hens chicks look exactly like the one you are asking about. Half hatch out pure black and half come out white with the black spots like that.

You can always name them after the puppies from the Disney 101 Dalmatians movie and use the fact you have 98 more names to go as your excuse to get more lol. Chicken math at its finest

Thank you for that explanation! Let me know if I got this....

dominant white + red/buff = dominant white carrier (F1)

F1 + black = splash look-a-like, but not really splash. Only half the kids would look like this though because the F1 parent has only one copy of the dominant white gene.
Sorta....

Except all of these things are controlled by multiple genes, so it's not a simple dominant/recessive model. And, as others have pointed out, blue/black/splash is controlled by a whole 'nother set of genes yet, as is barring, duckwing patterning, etc. etc. etc.....

Let me try showing a simplified model (with the caveat that I'm still learning and while conceptually correct, may not be strictly accurate). Added the Bl locus which is for blue/black/splash just for illustration.

E locus I locus Bl-locus
(black/white/wheaten, etc) (dom white/not) (Blue/Black/Splash)

Black Aus E/E (black) i+/i+ (not white) (bl+/bl+) no dilution
Buff Orp EWh/EWh (wheaten) i?/i? (hidden surprise) (bl+/bl+)
Babies E/EWh (black, recessive wheaten) i?/i+ (see below) (bl+/bl+)


Splash Aus E/E (black) i+/i+ (not white) (Bl/Bl) double diluted


Above you can see that the i?/i? for the red bird means you can't see what is there. It could be:
1. I/I then all offpsring will be dominant white with black spots (dalmatian, lol). Genetically they will all be I/i+.
2. I/i+, then half will be black (i+/i+), half dalmatian (I/i+)
3. i+/i+, then they will all be black (i+/i+)

And that's your science lesson for today haha.


I learned all of this from http://kippenjungle.nl/basisEN.htm, which has all of this info and way way way more. :)

I'm sure this is very helpful for many but with my work/education schedules conspiring to kill me, I maintain a good relationship with a Savant who is willing to help me out of such ditches from time to time.

If I ever get educated, I'm seriously thinking of some courses that will cover poultry color genetics...My employer will cover the cost if I put in the time...
 
Newbie to chickens here... one of my pullets is supposed to be a Black Australorp. She is 9 weeks old. Not seeing any of that green sheen to her feathers yet... does that come in later? What age does that show up more? Sorry if this is a stupid question or if someone already answered. I have been noticing she has some grey/white tinted feathers near her legs but otherwise is all black. So I wasn't sure if she was really a true BA. Got the ladies from a feed store that gets them from a hatchery.

This pic is at 8 weeks old... she is camera shy so this is the 1 out of 38429 photos where she is actually in focus!! haha.

Hi and



She will molt again at about 16 weeks old and get adult feathers. The green sheen will be there after that.

She looks like a nice one!
