Sex linked chicks

[Cheviot]

Hi,
A couple of questions about producing sex linked chicks, the way I understand it works is by putting a genetically gold cock onto genetically silver hens, resulting in yellow male chicks and brown female chicks, that bit I can get my head around.
Now for the stuff I'm not sure about :? , usually when producing sex linked chicks, two different breeds are used eg. Rhode Island Red cock, Light Sussex hen, but does it work when you use different coloured birds of the same breed, eg. Gold Spangled Appenzeller cock, Silver Appenzeller Hens?
If it does work, all the females would be gold spangled, but would the sex linking still work if you were to breed from those females?
Thanks ,
Sue

Very interesting !

I'll tell what little I know and we did have a not very in depth discussion on this before.

Gold cock on Silver hen is right, and only this way round.

It can work within a breed as well e.g. Buff sussex cock on Light Sussex hen, and only this way = Buff pullet chicks, White males.

Assuming Appenzellars are genetically Gold/Silver it should work for them as well (gold over silver).

As far as I know, the golds would function as pure golds but the only reason I have for saying it is that Buff Sussex hens have been produced fathered by the Lt Sussex male to improve the egg laying of the Buffs which would be needed as breeders in future generations.

I hope others will be able to shed some light.

Hi,
Thanks for the reply Chuck 17 , I didn't know wether or not it would work when using the same breed, it will definately be useful for me, as I breed Gold Spangled Appenzellers.
I'm still unsure about how the offspring will work out, as I suppose in theory although they are gold coloured, will they not have inherited a silver gene from the sire, which would perhaps not make them genetically gold? :?

Yes it's your last para. I'm not sure about. Strangely, I was going to try this with my Gold Aps i.e. mate them to a Silver male mainly to try to clear up the black marks on the tail feathers. However, I decided I didn't like them as much as I thought I would, so they all went ! Not enough eggs really and a bit small.

I'll see if I can contact anyone with a bit more brain power !

Sometimes it's hard to get people to give an answer. I wanted to mate my Buff Leghorns to the Whites which are outstanding layers to try to increase the egg numbers of the Buffs and to try to refine them a bit as they are a bit hefty for my taste. In the end decided to 'suck it and see' which I did & produced all white hens, some of the males having gold shading on the back and these I will mate back to Buff hens and the White half Buff hens will be mated back to Buff in hope that they will produce all or some Buff ofspring. It's one of my projects for this year as the hens are now in their second season of lay (I don't breed from first year birds).

Hi,
I find the genetics behind breeding really complicated, just when I think I understand how it works, I find out it dosen't , I have a project on the go at the moment, trying to breed a new colour, which I thought I knew how to produce it, but the genes aren't behaving as I expected. Hopefully I live long enough to see it through :lol:

I'm OK on the basic dominant/recessive and a little bit of practical sex link but when talk turns to what colours are attached to what alleles, I go off to make tea or muck out !

Sent the question out to three people I thught could help.

One didn't know. The other two said as far as they were aware the Buff pullet chicks produced from the Buff Sx male x LS females would be genetically gold and would breed true. The White males from the mating would not be.

This should apply to all gold cross silver matings but genetics being what they are other factors sometimes come into play

Room for some experimenting I would have thought.

Hi Chuck,
Thankyou for asking people about it, like you say genectics don't always work out the way you expect 07 .
I was hoping to try and hatch some sex linked appenzellers this year, but finding a good silver cock bird is proving more difficult
than I expected 06 , so it looks like it might be next years project.
Thanks again for the info,
Sue
