Rir too x Buff Orpington or Silver laced Wyandotte

The wild type down is a default down color and when genes are mixed the down color has a tendency to be expressed as pseudo-wild type. In your case, the rooster is brown and not wheaten at the E locus. Check the under color on the rooster- it should be gray ( if he is brown) and not a light reddish/whitish color ( if he is wheaten). The two chicks with the lighter down color are most likely from the buff orpington cross.

I was thinking that too Tim... there are some RIR lines that produce Striped looking chicks so I was wondering they are eb


Okay folks. Question for some of the old timers. lol Many many years ago when I was just a kid, my parents always had RIR's. Not from hatchery but from other local farmers. Dad and mom always let the hens set and raise chicks to replenish the flock because we butchered both hens and roosters. When our chicks were first hatched they looked like little chipmunks (ground squirrels). They had really black stripes back both sides of their backs and on their heads. I haven't seen this for a long long time.

Recessive wheaten or wheaten and brown heterozygotes can also produce the down color. I have also seen brown chicks that had that type of down. I would go with recessive wheaten with rhode island red.

Check cornish game- recessive wheaten

Smyth segregated recessive wheaten from rhode island red along with wheaten.

The under color on the bird will tell you if the bird is brown or wheaten. Brown birds have gray to silver under color while wheaten birds have a cream t white under color. It depends on the genotype of wheaten bird if the color is reddish, cream or white.

Thanks everyone! That's all very interesting.
I am going to go check my birds and get this all figured out just as soon as I get over the flu:/
 
Ok, I'm so lost with all this genetic stuff lol. It is very interesting so I'm trying to understand. I looked at my roo earlier and he is the same brownish red color under as he is on top. I didn't get super close though bc he is mean and would love nothing more than to spur my eyes out;) I noticed one of my light colored chicks looks chunkier than what I'm used to in the face and has these little patches under his mouth. I'm sure it's fine it's just different but then again i have never hatched any chicks from my wyandottes and buffs before.
 
He/she also kind of stays away from the other chicks and seems to sleep and not want to keep his eyes open. Here is a pic....

Its not from your Buff Orpington, they don't carry the Wild Type (e+), chicks born with the Wild Type (e+) gene are born with the stripes on their back and the stripe on their eyes. Buff Orpingtons have Wheaten based genes Wheaten (eWh), that's why they are born with light legs and light down. Rhode island reds don't carry the Wild Type (e+) either so they wouldn't pass it on. It looks like they are from the Silver Laced Wyandotte. If you cross a Rhode Island Rooster to a Silver Laced Wyandotte female you would get red sex-link chicks.
