Barred Rock color differences in 4 week olds

Blimey, that is bad luck.

Real bad luck... I would have been happy with 10 pullets.....

My birds were extended black and segregated from two heterozygous dominant white leghorn hybrids. My bird was a female and only carries one barring white gene. Males would look like the bird you posted. I can see the efects of the mottling genes in his wings-the primaries in the wings are white.

Mottling and barring on a wild type down produces an almost white male. This is evident in the 55 gold flowery leghorns produced by Silverudd.

Chris,

A show quality Barred Rock was analyzed and the bird carried columbian ( It was Smyth or Carefoot???). That would explain using columban to improve barring. The barred rock - hatchery grade-(One bird) I worked with also contained columbian.

The 4 females out of 50 eggs is strange. The probability is about one in 2000 that that would happen???????????

Im in that same boat as you.. I got 4 Rhode Island Red pullet out of about 50 eggs hatched.

Yeowch, now them's some bad odds, I was whining over about 70% males... Now I feel oddly better.

Then again I have to scrap the ENTIRE project and start again anyway. Sigh.

I'm keeping four rocks, a true black, a blue, a partridge and a black bleeding red showing partridge on the wingbows - kind of pretty and VERY large. The rest are Delawares - figure I might as well have fun in the meat/layers pen while I get reset for partridge.

Thank you all for being on these threads and helping me and others sort out the genetics fun...

The odds were against me this year.. I'm just glad I didn't go to vegas!! With those odds it wouldn't be pretty...

Galaxiedriver,

Welcome to the forum. I too am from central Missouri- I live near Jefferson City and
have visited Griffith Hatchery.

Tim, Thank you. We have lived in Columbia since '79.

I visited before Mr. Griffith passed away and the new owners purchased the hatchery.
I was hoping that I would be able to purchase the hatchery but I missed the
opportunity. I was going to produce unusual variates and provide them to the public.

We were going to go to Griffith's to pick up our birds, but they were coming to Columbia and so dropped them off. I would like to visit there one of these days.


Was the down color on the male chick the same as the other chicks ( black with a
white head spot) and did he have tail feathers before the other birds. If he has the
rapid feathering gene (Krys posted this), he would of had a tail way before the
others even showed much of a tail. At two weeks his wing feathers and tail feathers
would have been noticeably longer than the other birds.

Yes on the color but with a little more white. Here is a photo of the brood at one week and he stands out a bit. He was the first to develop tail feagthers but a couple others were not far behind. At 3 to 4 weeks he looked pretty much like a full grown chicken, only tiny.

Here is another and Rocky is the one in the center rear. Note the line through his eye that is mentioned in an earlier post.

Does the male bird have any white primary wing feathers? If he does- then he is carrying
mottling which would explain his color. Mottled birds on extended black usually show a
pied juvenile plumage but I do not see that in your bird. This picture below is if a barred
and mottled bird I produced.

No on the white primaries.



Normally barred males are a lighter color than the females because males carry two sex-
linked barring genes. The barring gene expresses a dosage effect upon the plumage of
the bird. One allele(gene) or one dose produces a bar that is so wide while two sex linked
barring genes would be considered two doses and the bird has much wider bars.

To keep up with group I see I am going to have to study some genetics. Very interesting conversation going on here.
