Sex- linked Information

I hate to be dense, but this genetic stuff is over my head. I want to do some sex linked meat birds and was wondering about the following scenarios:
I have a marans roo who is blue (say that three times
If I put him over delaware hens for a meat bird, would they be sex linked? If so, what color?
If I had a delaware roo over blue or black marans, would they be sex linked? If so, what color.
Thank you any and all for answering. I should have paid more attention in college in my genetics class instead of recovering from my hangover from the nights before!!!
Any other good combos I could do??????????

I have a splash Marans guy that I hatch eggs from a Del hen they look like a blue almost barred bird never had any girls hatch from that cross but the boys are huge and grow fast and taste like chicken

Click on the very first page of this thread and look at the first post. It talks about sex link crosses. You can't cross a barred rooster and expect to get sex links. Only the hen can be barred. Check the first page, it explains a lot. Your first cross might work to produce Black Sex Links. Sex linked meaties would be cool. A Dark Cornish roo crossed with your Delaware hens might bump up the meaty or at least maintain it.

Does anybody know how barring + mottling works on other backgrounds than e+?
I am (slowly lol) reading through the text for Silverudds multiple cock shifting system (SMCSS) and it is mentioning something interesting
Quote:
My mixed flock is giving me barred and mottled females and it's indeed a quite nice color combination. In theory I should also get a full range of Bb & BB males in Momo and momo, but while I got the regular BB and Bb ones and some very nice Bbmottleds combining the patterns, there were NO white birds. So I'm wondering if statistics is just playing dirty tricks with me and there simply were no mottled BB cockerels (out of 21 male chicks) or if it's the different E locus (mainly ER with some E and Ewh).
Thinking about it, I did get some suspiciously light BB cockerels this year, with a pattern of unusually wide white but thin colored bars. They don't seem to be mottled, but mottling on barred birds is often kind of hard to see, so I could be missing it.
I really enjoy the barred&mottled look of the girls and was planning to keep a mottled Bb male for them, to avoid having to keep a bright predator bait rooster. But now I am kind of hoping that the pattern combination is not giving white roosters on ER and I could keep a BB rooster instead.

I was looking for pictures of the mythical "Ancobar" online, to compare them with the FFF and see what is meant with "e+ being far superior to E" in producing easily auto-sexing chicks, but had no luck.
Does anybody have another literature recommendation, links, pictures or other experience with this issue? Or dares an educated guess?

I have produced barred and mottled birds on extended black. All you get is chick down similar to mottled down. Are your birds gold or silver? You get the white males with the silver flowery leghorn. The gold flowery leghorn males should have some buff color in their plumage. I have never seen the golds so that is a guess on my part but they should not be white like the silver males- some of the color from the gold alleles should be visible in the plumage.

This is the only picture of one of my females I could find- she is a juvenile.

She's pretty

, there's just something about the bars ending in a white dot which I really like.
So you mean the white chick down for male chicks is just present in the e+ chicks and on E or ER it would just be their regular down with the head spot, mottling in baby feathers and they turn white later? Hmm yes, that would indeed make e+ much better for sexing chicks, like the text was hinting at.

My flock is golden based and the chicks so far had just their regular chick down with the barring head spots. No white chicks and just a few yellow ones which always turned out to be wheaten. Thanks to rapid feathering I can usually tell if there's mottling at about a week or two, at least on the E or ER birds. However my mottled pullets and B/b boys are a lot darker than the one on your picture

I guess that's because mine have mediocre mottling and messy cuckoo barring with some extra melanizers.
I still need to take non blurry pictures of the light BB cockerels which are not really white but could have mottling.
All I have uploaded now are from a typical dark hen and chick, the other hens with more mottling are molting.
B/- mo/mo hen
B/b mo/mo chick

I heard the same about the silver 55Flowerys. White chicks and roosters with a few random gray flecks. The gold ones are supposed to be white chicks, too. And the roosters should have gold flecks instead of gray ones and some gold leakage on the shoulder area. But there's very few people keeping the gold variety nowadays, so reliable informations are hard to find even in Swedish

Silver is much more popular and the few pictures of roosters I could find showed silver roosters. Of course. Arg.
But most times people just seem to take pictures of the hens anyways, maybe because the white roosters look kind of plain compared to them, who knows.

I just have a question about mixing some black sex-link hens with leghorns.... I currently have 2 runner ducks and 2 leghorns ( a male and female of both) and I am trading my Leghorn cockerel for 3 black sex-link and 1 red sex-link, I was told 3 black star and 1 red star, hens all about 1 year old. Would it be OK to put these 4 with 1 leghorn pullet and the 2 ducks? Will it just be the normal pecking order thing or could the 4 gang up on the one? I think the ducks will look after themselves as they are bigger. Can someone please inform me...

I'm trying, but having a hard time figuring this out! I want to put a splash Plymouth rock with barred rock pullets to produce sex-link barred blue males and blue females? If I cross the resulting blue barred cockerels to the blue pullets, can I expect splash males and females, barred males, blue barred males, blue males and females,and black males and females, ? How about barred females? Thanks for any help, I am enjoing this thread, as long as I don't try to read too much. That results in a head ache!! ........stan
