Genes that would make a chick have spots?

[HarmonyFox]

I know this might be a hard question but I just hatched out two of my own chickens eggs. One is yellow with three black spots on it's head and one feint black spot on it's back. I'm curious to know if anyone could help me figure out the father or if I'll have to wait until it's older. I had a speckeled Sussex rooster but while they were incubating he got taken by coyotes so. I also have a Cornish cross rooster, silver laced wyandotte rooster, and a barred cochin bantam rooster. The mother is probably a buckeye, or road island red only because I assume my other hens wouldn't have yellow chicks.

Those chicks (the one on the left in both pictures, anyway) appear to be single factor dominant white. It will mature into a largely white bird, but will retain those black patches. White Leghorns are Dominant White, RSL have it, and any bird that is 'Pyle' coloured.

ETA: Possibly your Cornish X? I'm unsure of their genetics, though a double-dose of the gene generally results in a clean white bird, so it would fit.

The chick to the right's father was the Wyandotte as it has a rose comb. If the other chick is the same, then the Wyandotte is the father to both. Silver would produce red-yellow chicks with the red hens (though not sex linked as hen was red while father was silver...all chicks will be fawn colored).

I can't see the other chick's comb.

But I can say, since no foot feathers, the Cochin is not the father. Nor does it look to have Cornish influence.

Does it also have a rose comb?

Hadn't noticed the rose-comb there, @Lady of McCamley. It complicates things rather, as the chick is definitely Dominant White (those black spots), therefore if the Wyandotte is the father, the mother cannot be either Buckeye or RIR. @HarmonyFox, would you be so kind as to list the hens you have?

ETA: Just realised that the chick with the rose comb is not the one with the spots, therefore yes, that one is unlikely to be Dominant White. It appears to be gold based, however, which would not fit with a Silver father (unless he is hiding gold). If the father is Silver, all offspring will get one copy of Silver, which is dominant over gold. Female chicks only have one 'slot' for ground-colour, so are either Silver or Gold, whilst males have two, and can be both; 'fawn'.

So the non spotted chick actually has a folded over single comb. And the spotted looks single too but just smaller.
The hens who were laying when I got these eggs would be,
RIRs
Buckeyes
Black sexlinks
1 Isa brown (70% positive she's the mother to the non spotted one and she's a bit small for Big Bird (Cornish cross) to mate with her. He has a wide stance so she just walks out from in-between his giant dinosaur legs)
1 Phoenix
1 cubalaya
1 Cornish (pure Cornish not a cross)
1 single combed silver laced wyandotte
Here are face pictures of the chicks though
Non spotted one

Spotted one

So would all my Cornish cross's chicks have black spots? He's made by mating a female Cornish with a male barred rock. I love genetics so I would love to learn about them if I can

Cornish crosses do not contain barred genes. The industrial Cornish cross was originally bred from White Plymouth Rocks and White Cornishs. The bird has been bred selectively for over many decades to produce the Cornish cross.

The Isa brown could have dominant white. Does she have a white tail?

As the flock contains mixed breeds, it's difficult to make any definite determinations. As the birds grow, you're likely to see more characteristics show themselves and indicate possible parentage.

Thank you! I probably read that and got the two mixed up lol I was thinking it seemed really weird for them to come from a barred chicken lol

No she's all red with a small green collar of feathers around her neck and a few green feathers on her tail. She could not be an Isa brown. She was in the bin of phoenixes and cubalayas and I emailed TS about her and they said she's probably an Isa brown. So lol it's not super definite. She's so sweet though I love her. Her name is Clementine.
