GENETICS: What did I (ok, the birds) make?

[Rogue_Woman]

Hey folks, I've got some brand spankin new chicks that I just hatched out that are sex-linked, but I can't figure out which is which. I did a reverse sex-link to see whether or not they would still link the same, so here are the results:

The mother is a RIR hen and the father is a White leghorn rooster. So, it's gold female X silver male...is the sex linking the same as the standard silver female X gold male where the chicks are hatched as gold female and silver male? Is that confusing enough?

Hopefully it's not backwards, because I ended up with 3 gold and 1 silver, and that sure would be a nice female to male ratio! Here's pics of a few of the little ones, and thanks in advance for any help!

I love the look on the broody's face.

It is so cute. However, and I could be totally wrong. I don't think the chicks will be sex-linked at all. It only works the one way. Hopefully someone will chime in and let you know for sure.

She's a great momma and is so darn tame she doesn't mind a bit when I'm in there 50 times a day being nosy with my hands under her

I certainly wouldn't deal with me as well as she does! Too bad they just don't stay broody all the time, she's perfect!

I hope somebody has experience with these crosses, I'd really like to know! Of course, I'll know soon enough when they feather out I suppose, but I'm as impatient as they come.

 

[Rogue_Woman]

any takers? Someone here has to have done this before!

I am pretty sure they wont be sexlinked. The yellow one will be white with a couple black or red feathers and the red chicks will be red. It is kinda like crossing a BR roo on RIR hens, it wont be a sexlink.

You have a RIR/leghorn cross.

The sex link hybrid to my understanding is very specific.

Red male for the father with either a Rhode Island Red or a New Hampshire being used as the sire.

The females are Barred Rock as the mother and resulting chicks that are male feather out as barred with a few red feathers. This pairing is the black sex links sold by many hatcheries.

Red sex links is too much to type out so i am going to copy this from feather site

Red Sex-Links are the result of various crosses. White Rocks with the silver factor (the dominant white gene would produce all white offspring) are crossed with a New Hampshire male to produce the Golden Comet. Silver Laced Wyandotte crossed with New Hampshire gives the Cinnamon Queen. Two other crosses are obtained with Rhode Island White x Rhode Island Red, and Delaware x Production Red. These two crosses are simply called Red Sex-Links. Males hatch out white and, depending on the cross, feather out to pure white or with some black feathering. Females hatch out buff or red also depending on cross, and they feather out in one of three ways.

Buff with white or tinted undercolor (such as Golden Comet, Rhode Island Red x Rhode Island White)
Red with White or tinted undercolor (Cinnamon Queen)
Red with Red undercolor (Delaware x Production Red) (In this color pattern it is almost impossible to distinguish daughters' color from father's color.)

To my understanding you do not have sex link chicks.​

Thanks a bunch. I guess I just have to be patient and see what I end up with. At least I did get the one white chick with black spots, which was what I was really going for!

"Brown Sex Link
Brown Sex Links are a breed cross using Rhode Island Red males and silver factor White Rock females. The chicks can be separated by sex at the time of hatching since the females are primarily red and the males are primarily white. Commercial producers of brown eggs sometimes use this cross, which has excellent livability and efficiently produces large brown eggs. Hens from this cross weigh about 5 1/2 lbs. and can be salvaged for fowl meat when their use for laying is over.
Mature males will weigh approximately 8 lbs.
Black Sex Link
Black Sex Links are a breed cross using Rhode Island Red males and Barred Plymouth Rock females. The male chicks have a white spot on the top of their heads and can be separated from the solid black female chicks when they hatch. This cross, which is used in commercial layer operations, is an efficient producer of large brown eggs. They have excellent livability, and hens from this cross weigh about 5 1/2 lbs. and can be salvaged for fowl meat when their use for laying is over.
Mature males will weigh approximately 9 lbs.
Gold Sex Link
Gold Sex Links are a breed cross using Rhode Island Red males and Rhode Island White females. The female chicks are streaked with red or gold and can be separated from the solid white male chicks at one day old. This cross, which is one of the most popular used in commercial layer operations, is an efficient producer of large brown eggs. This outstanding cross has excellent livability, and mature hens, which weigh 5 1/2 lbs. can be salvaged for fowl meat when their use for laying is over.
Red Sex Link
Red Sex Links are a breed cross using Rhode Island Red males and Delaware females. The females are primarily red while the males are primarily white; therefore, the sexes can be separated immediately following hatching. This layer is used in many commercial layer operations. They have excellent livability, and are very efficient producers of large brown eggs. Mature hens will weigh about 5 1/2 lbs. and can be salvaged for fowl meat when their use for laying is over.

So i have a white roo with a few red feathers and 2 black ones - does that mean the mom was some kind of red breed and the dad was some kind of silver? Just trying to get a handle on color genetics myself.

 

[Rogue_Woman]

maybe dad was a white roo and mom was a black sex link? That might explain all 3 colors...heck, who knows, I'm even more confused! (Note to self: learn more about color genetics). Apparently it's not just one pair of alleles responsible for coloration, It must be an entire alu with several allele pairs, and some are marked by dominant/recessive, and some can blend allele traits. I need a crash course!
