OOOOOhhhh. I want to play <3 I love trying to predict what my mixed breeds will be. (I've actually bred so that my generations have certain feather traits so that I can tell age by plummage).
My predictions:
Trait: Mother--Father
Comb: Peacomb--Straight/Single comb
Peacomb is a dominant trait meaning only one P gene needs to be present. Since momma is a Easter Egger mix, there's no way of knowing if the is Pp or PP (but she looks single pea as it's not a strong pea comb). If Pp, 50% of her offspring will be pea combed and 50% will be single combed as single is absence of any Pea or Rose comb genes (which is poppa). If momma is PP, then 100% will have a single P dominant gene and present a pea comb (though not as clean as PP). Sometimes single pea looks a bit different than double pea. In the photos, I'm not seeing any pea combs, but it's really hard to see them at very young stage. I'd be surprised if the all end up single as momma does have a pea to pass.
Color/Pattern: Brown mottled with gray wing tips--Black and white barring with buff tints.
Poppa is a Cuckoo cross (with buff) so has a single barring gene and buff bleed through. That means 50% of the time he will pass barring to the offspring, male and female. No sexable chicks as his barring is on the Z chromosome passed equally, 50/50 (unlike the female being barred passing the Z barring chromosome and only her male offspring is barred). I don't see any head dots on the chicks, so you may not have any barred that came through. Hard to tell white dot on pale heads, but I think they don't look like single barring.
Momma is mottled. Mottled is recessive meaning you have to have 2 mottled genes. She passed one, so no mottling on progeny.
As to base and secondary coloring, wing tips...that gets a LOT trickier. Your rooster has a lot of buff bleed through, and momma is base brown/partridge like (I may not be using all the correct technical terms as I haven't got my head around all the secondary colorings).
Barring is dominant. Poppa is single barred. Any of those would be apparent with a white head dot typically on a darker body unless diluters such as buff are applied. On the 50% of chicks that don't get the barring gene (by statistics), I predict a brown partridge base (the chipmunk colored chicks). I think some buff passed through with the gold chick who I think will be predominantly gold, not barred, possibly more red based as buff is complicated taking several genes to create the pure gold on the body. I doubt you've got all that. The white chick with black head streak....hmmmm...I think that will be a white body with black secondary...not sure pattern.
Keratin: Dark grayish feet and beak--White feet and beak
Feet and beak can be hard to determine for me. I've had a lot of variation that didn't seem to follow patterns. My Black Copper Marans bred to Barnevelder produced some yellow feet. Maybe someone with good feet genetics will chime in. I think that will be a crap shoot. Typically pinkish chick legs turn white, yellow stay yellow, dark legs stay dark.
Egg color: Blue eggs--Undetermined but both of his parents' breeds are brown.
For egg color, you've got as stated an Easter Egger girl. Since she is a mix, I will assume she is single blue shell O. That means she is Oo to pass along a dominant blue shell gene to 50% of her offspring. That means 50% of them will get the blue shell gene, and 50% of them won't. Daddy comes from brown laying lines, so we can reasonably assume he has some of the 13 genetics for brown laying. His progeny will carry the genetics to create hemoglobin wash that coats, like paint, the shell of the eggs coming down the egg tract. All his daughters will have some, more or less, of those genetics. Typically I see midway color between two brown parents (I breed for dark brown and olive).
Of the 50% daughters that have the blue shell, brown wash over blue shell produces shades of green. Of the 50% of the daughters that did not inherit the blue shell gene, they will lay differing shades of brown depending upon which brown genes they inherited.
Wattle: Beard--No beard/standard wattle and ear.
My experience is the beard is about 50/50 with progeny. Same with foot feathering (if you had any). I'm not seeing muffs on anyone in the photo. If that's mom on the left on the bottom photo, she doesn't look muffed, so she won't pass any muffing down.
My predictions and thoughts.
