Excuse my ignorance...but what is an Olive Egger Rooster good for?

[nicalandia]

His barring will pass to all offspring, both male and female, so you can follow the barring to distinguish from blue gene vs. brown gene

So far no linkage have been found for the Blue eggshell gene O/O which is Autosomal and the sex-linked barring gene(one is Autosomal and the other is sex-linked)

Very true, but I find knowing your lines with telltale physical features helps with keeping up with the flock, validating records, and quick observance of the likelihood of what genetics you've got.

Pea comb is not causative for blue shell genes merely coincidental to location. It works if there are 2 blue genes, and somewhat if there is 1 blue gene, however pea comb is dominant over single comb, which is the comb type of the typical brown layer line, so pea comb will present with or without any blue shell gene from F1 forward.

Always best with an unknown roo to do test breeding before relying on his progeny for future breeding or sale.

Good discussion though.

I agree and it has been my experience that I can rely on the pea comb gene for the blue egg shell in about 90% of the times, that is the only way I have to pick up roosters of crosses of EExSingle Comb breeds, the other day I missed a sale on a Single Comb Hen I was trying to purchase to incorporate it into my ISA brown breeding stock(to create more Isa brown type hens along with Isa Green hens)

Said hen(not mine for being short on the ad)

Interestingly enough, Dr. Punnett Chilean stock he got were Single Combed and that is the base for the CL and Isbars

Yes...exactly...the Chilean stock was an odd assortment of riff raft to be certain....some muffed, tufted, tailed, rumpless, blue eggs, brown eggs. It took the doctor (forgot name) at the Santiago (World's Fair) a number of generations to breed them to get some sort of consistency...that was exhibited at the World's Fair and alerted the world to the blue gene again....but what we got was definitely a mixture.

Interesting history of our blue eggers...and one things certain about genetics, it can always surprise you.

....or if you don't want to go thru all that, put them on the grill
That's where these BCMxCCL guys are going in another month or so.

 

[Lady of McCamley]

@aart And yes, that is a quick "do over" ploy to wipe the slate clean and fill a plate.

Curious...I'm getting about 50% carry forward on the head crest from my CL's.

What do you experience with the BCM/CL cross. (I'm seeing some crests, but maybe not all?)

I like it when that happens as it is another sign of the genetics for blue to follow in a flock of mixed birds running around. I have noticed that the CL white ear lobe seems to always carry forward.

Just curious.

Pretty small sample here but the 6 pullets I've kept all had crests.
Muddy olives due to pale blue.
As for the males, they all went by 16 weeks so hard to say what they'd have after last juvenile molt, but as I recall most had some crest feathering.
