Possible Stupid Sex Link Question

[The Moonshiner]

@The Moonshiner we had this discussion a while ago about my BCM rooster mating with my CCL hen and producing sex linked chicks, which is exactly what I got. Two hens and two roos . Now, I also produced a sex linked chick (roo) from my BCM x Cuckoo Marans. If this roo is mated back to one of the two hens from the BCM x CCL will those chicks also be sex linked. I'm trying not to get dizzy here....

Nope.
With your two original crosses the barring from the hens was the key.
With the offspring they're backwards. Pullets aren't barred and cockerels have one barring gene.
You would get half barred chicks and half non barred chicks of each sex.

Well, phooey.... thanks for the info. Greatly appreciated.

Breed one of your cockerels from the BCM Xs CCL back to the CCL hen.
You should get half barred and half non barred pullets and half single gene barred and half double gene barred cockerels. Double barred will look lighter color when they get feather in. Single gene ones will look like the pullets.
Pick any double gene barred chipmunk striped chicks you get and breed them to any chipmunk striped pullets.
You should then hatch auto sexing pullets and half auto sexing males and half single gene barred cockerels.

Do you have all this info in your head? I am having to write all this down. Thanks again, it just so happens that one of the roos from the BCM x CCL is a darling. Comes up to me, likes to be picked up and taken for an adventure and will sit on my arm (pooping, of course) and hang out while I drink my tea. I think I'll keep this one and use him for your instructions. Of course this means I have to mate him back to his mother.....

Mother son isn't an issue in the chicken world.
You can actually use any CCL hen though.
You need to get back to the duckwing chipmunk chick down of the CCL.
Your cockerel will only carry one gene for it so he will produce half his offspring with it if bred to any CCL hen.
Same with his barring gene.so only half will be double barred.
You get a male chick that is double gene barred and striped he'll be the key.
He should be an olive egger or at least a green egg layer. Genetically anyways. I know roosters don't lay eggs.
Breeding back to the CCL will increase your odds of continuing the blue egg genes. Again half his pullet chicks should get blue egg gene from him. All will get one from their mother.
Then you'll just have to see how the dark brown egg genes hold up to see how dark of green they lay.
Oh and yes its in my head. That's the only way I don't lose it.
Or at least the only way I don't lose it yet.

Excellent. I am looking forward to seeing how the eggs are from the hens of the BCM x CCL. The CCL lays a lovely, quite bright, blue egg so I am hopeful for a green rather than an olive egg. OK next genetic question. If I sell the roosters of the BCM x CCL, and I have to give a description of possibilities of egg colors from pullets of these guys, what can I say? I mean obviously it is going to depend of the egg color of the hen they are mated with but is there a greater possibility of olive eggs? Sorry if this is a silly question. Thanks for the time, again!

I guess I would call them olive eggers or Easter eggers and leave it at that.
It would depend on hen to determine and that'll end up with quite a few different possibilities. Too many to try to explain IMO.
For your information they carry one gene for blue eggs and one gene for non blue (white) eggs plus some dk brown egg genes.
Just from their side they would produce about half with blue egg gene and half without blue egg gene. They would almost certainly pass on some brown egg genes also.
Mostly they would produce brown or green egg laying offspring.

Great. Thank you.
