Is the chick blue or black?
Im only on a phone so hard to tell with such a small pic to look at.

Are your brahmas pure bred?
I would agree that one of the brahmas is one of the parents.
Buff brahmas are gold based. Agreed that the chick looks silver based but either way it has to be silver split to gold.
If the brahma is the dad and a silver based hen is mom then it would get silver from mom and fold from dad. If the dad is silver and the brahma is the mom he would get silver from dad and gold from mom. So either way he gets one silver and one gold and its not going to narrow down which brahma is involved.
If the chick is blue im gonna say the dad is your blue cochin. If the chick is black then back to who knows.
Your dealing with too many unknowns to get a good picture. Its kinds like trying to put together a puzzle without the picture of what it looks like when complete.
Sure you can try to put it together piece by piece and some pieces are going to be easy to see what they are but a lot of the other pieces are going to not make since and be hard to figure out just where they fit in.
Seems I remember from other posts that your cochins are mixed colors. There could be so much going on under whats showing that you may never figure this out.
When your breeding crossed chickens or cross colored chickens more often then not the offspring end up completely different then how the parents look.
When you bring in so many unknowns then it just continues with more and more unknowns.

I'm on a phone too. I got my brahma bantam roo from Murray McMurray hatchery, the buff brahma bantam hen came from my pet chicken.

My brahma rooster has has offspring that have had green eyes before and this chick has green eyes. Also I think it hatched from a Cochin egg but it's possible the egg could've been from the brahma hen too.

The chick was black and white when it was little however I currently have chicks that were black when they were little but are feathering out blue. I don't know if the feathers it has now are blue or just faded black cuz he's young.

You're not going to get yellow legged, black nailed bird.

Single comb is recessive - pprr. When you breed to a bird pure for pea comb you get all pea combs (a chicken pure for pea combs is PPrr). Pure for rose is ppRR. So if you breed a single combed chicken to a pure pea, you will get pea combs. To a pure rose combed chicken all rose.

Hmm....Interesting.
Now if I did it the other way around(Wyandotte, Sumatra, Austrolorp Roo to a BR hen)Would that be totally diffrent, Comb wise?Or same?

Same.

I should add to my first statement, that is only the case in a purebred rooster. I mean that in your case with a Delaware roo, all chicks will be barred.

It doesnt have to be purebred but it has to have two copies of the barring gene to throw all barred chicks. One copy will give 1/2 barred and 1/2 non barred.
I assume when you say purebred youre meaning that it has to have the two copies of barring.

Yes, I meant purebred as in pure for barring - two alleles. So, a pure Del roo would throw all barred chicks. If he was barred, but only one copy, it would be 50-50 like you said.

If you think he is the dad what were the choices for the mom, again?

I think it hatched from a Cochin egg, I have a splash Cochin, lavender Cochin, and barred Cochin hens, one of each color. I have a partridge hen too but she was broody.

Also when I bred the buff brahma roo with my mottled Cochin hen (both have orange eyes) I got two green eyed chicks. I kept the female chick and i bred her to my blue Cochin rooster and got a green eyed chick. I think. Her eyes look green.

Its not barred so couldnt be from the barred hen. The splash hen would have to pass a blue gene to its offspring. If the chick is blue its hers. If its black it cant be hers.
If its black then it has to be from the lavender hen.
Thats assuming the brahma is the dad.
Thats the easy answer. Your lavender could also carry blue and be the mom to a blue chick. Most people try to keep blue out of a lavender line so most likely she isnt blue but theres always a chance when you dont know her background.

Ok, I LUV Genetics.
But I'm bad at them.

I'm wanting to try to make a Silver Paced Austrolorp or Sumatra:
Barred Rock Rooster,
Bred to a Black Austrolorp, Black Sumatra OR a Silver Laced Wyandotte Hen.
My questions:
I'm not sure if this is possible.I want the bird to have Yellow legs, Black nails.Is that even genetically possible?
Alright, lets talk Comb.Austrolorp I have no problem with.Sumatra and Wyandotte I do.
How is it going to throw of the comb By breeding a Single Comb to a Pea Comb/Rose comb?

Hmm....Interesting.
Now if I did it the other way around(Wyandotte, Sumatra, Austrolorp Roo to a BR hen)Would that be totally diffrent, Comb wise?Or same?

Whats the barred rock for? Why have that in the mix?

I thought she was wanting to make a barred chicken, maybe I'm mixing it up.
