crested cream legbar hen x blue game mix roo = autosexing?

[kari_dawn]

So I have a clutch of eggs hatching, and some of them are crested cream legbar eggs. My rooster is a blue game mix, and when the first chick from a blue egg hatched, it had a white spot on it's head, which reminded me about autosexing. I know pure crested cream legbars are auto sexing...is it possible that I am hatching sexlinks?

You are hatching Sexlinks.. The males will have a cream head spot and the pullets will be solid black/blue with no head spot

oooh cool! Thank you for the reply! So, couch is a dude?

Do you have a pic of your rooster? If he is a mix he may carry genes that may or may not effect producing sexlinks. For instance if he carries barring genes he won't produce sexlinks.

I do have pics. I have lots of pics! I love watching him march around the yard.

Also, the offspring he has produced so far has been predominately blue (8)/black(2-one is the "mother" of the chicks that hatched outside, the other may just be very dark blue. it is the chick in question from the crested cream legbar egg)/splash(2-both from splash marans eggs, both with feathered shanks) the vast majority have been blue. He did produce one chipmunk, the biological contributor is a welsummer derived olive egger named Clifford. The second chick from Clifford came out dark blue.

Yes.

Wow, I really like him, he is Heterozygous Extended Black(E/e+) and heterozygous for Melanotic and possible other genes that are required to make a fully black bird(at least E/e+, Ml/ml+)

Awesome. Thanks so much!!

I really really like him. I don't know as much about chicken genetics as I would like, but he has thrown some amazing birds. I had an amazing little game mix by him, and from a buffy red female game...she was a gorgeous blue with very dark face (actually, all the chicks from that group had very dark faces...their combs and wattles were black when they were little, so I could see the melanotic).

She looked like a dark slate blue game hen with black comb and wattles (she hadn't reached pol...they probably would have turned red. Her sister's did, though she's not as gamey looking-probably from a different hen).

I really wanted chicks from her but alas a neighbor's dog got in and grabbed her, and she died within 15 minutes of the attack.

What is extended black?
