The Frizzle Easter Egger mom is likely a Splash with wild-type partridge pattern. The Brahma definitely has some mixed pattern genes. If he was a proper Blue Partridge, his chest would be solid blue. Brahma project colors are usually a real mess, genetically, and he is not an exception.

What does that make mine then? Where did the gold lacing/penciling on the feathers come from? The mother doesn't have that.
I can get a close up of the feathers tonight if it helps.

Both parents are red/gold base color. Both parents also have some penciling, so it's not crazy for their chick to have penciling. The rooster has at least a partridge gene, but he also has other genes that are interrupting how the pattern expresses. It's likely that he has some Buff in his ancestry. Penciling is kind of a default pattern. The amount of penciling and where it express can be influenced by many different genes.

So if I understand you correctly, we're then thinking that my chicken would be splash partridge like her mom, but with penciling influenced from both parent's genes which is what makes it more obvious in her feathers than her mother's?

As far as testing if it was splash versus a form of dominant white like with buff laced polish, would I just need to breed her to a normal black patterned rooster and see if all chicks come out blue patterned vs 50/50 black and white chicks?
 
She's actually a True Blue Whiting out of Arkansas but I'm sure there is some of the same mixes to get it but they are supposed to breed true to blue eggs. My other two don't have muffs and I think her comb isn't a true pea comb. My EEs look much much dif than her in pretty much every way but the muffs and beard. What is "columbian restricted"? I really need to learn more about chicken genetics. It's so fascinating.
Pea comb is incompletely dominant to single comb. That is why the pea comb is different. I was going to say more about the comb but I was not sure from the picture. Your bird is carrying one pea comb allele and an allele for single comb. I crossed pea comb birds with leghorns and the females combs were tall enough to flop over- with a pea comb like spikes on the distal end (end away from body).The blue egg allele is very closely linked to the pea comb allele- your bird may carry only one blue egg gene. The two, blue egg/pea comb are usually inherited together. Some birds like the legbars have single combs and lay a blue egg. The single comb allele could be linked to a blue egg gene and your bird would have two blue egg shell alleles.

The columbian gene is a gene that restricts black to certain areas of the chicken's body plumage. Namely the tail and wings with some in the neck hackles.

A good example of columbian restriction can be seen in a delaware. The columbian gene causes the white feathers to spread out over the entire body but very little into the black wings and tail feathers.

Another example of columbian restriction can be seen in black tailed red birds- like in the new hampshire. A new hampshire would have the same color as a wheaten but the columbian gene causes the wheaten color to change to the brownish/red color found in a new hampshire.
 
Out of curiousity what would this True Blue Whiting girls coloring be considered? She is my favorite in my flock color wise.

she is a melanized black breasted red phenotype. Her coloration would look similar to a light brown leghorn but the melanizing gene or genes are making her black.

Mother looks much like a frizzled red sex link- she is frizzled white tailed red phenotype. Her tail would be black but the dominant white is causing the white in her feathers.

The brahma does not have the phenotype of a purebred blue partridge. He is blue and most likely brown at the E locus but he is also columbian restricted- his breast should be blue and not reddish. If he is carrying the pattern gene then he has some of the genes needed to produce single lacing. The partridge genotype should be pure brown at the E locus and purebred pattern at the pattern locus- no columbian.


In the frizzled offspring she may be blue ( you can not tell because the dominant white is removing the blue) and she is predominantly white because she is brown at the E locus and the pattern gene- that explains all the white in her feathers. The pattern gene would add black to the feathers but the dominant white is preventing the black pigments from being expressed in her feathers- therefore a mostly white bird. Brown birds (brown at E locus) are heavily black stippled.

Ya I've been calling it a modified pea comb. I think the mix has leghorn in it to boost production so they are higher production blue egg layers. I think the combs will get big enough to flop as they aren't fully mature yet and still have been growing.
Thanks for the lesson. I'm still new to chicken genetics. I've messed with pigeon in the past but they are way more simple. Chicken genetics seem pretty darn complex.
