genetics i need some help

[squeak1387]

So yesterday I hatched out a fluffly 5 toed feather footed naked neck chick. You are probably saying, yeah that's gonna be a show girl, the only problem is the skin is not black. So now I'm totaly lost. What I've read says u get black skin no matter what when its mixed with a silky. And the only birds I have with 5 toes are my silkies. So can anyone help me out with this. Why would it have 5 toes but not black skin?

Because maybe your Silkies are poor quality hatchery birds?

That's the only conclusion I can think of, however, the fluffiness only comes from crossing back to a Silkie again or crossing F1 x F1, which can indeed lose the skin pigment, so the question is, are you sure you crossed back to the Silkie?

Have you checked your Silkie's skin? When from a hatchery, not all are dark skinned.

My silkies aren't hatchery bred, and they are all dark. I'm not even sure if there is silkie in it but I just assumed since it had the extra toe

Do you have any Cochins or Frizzles?

are the eggs from your own stock?

there are several breeds that have 5 toes besides the silkies, including sultan, dorking, faverolles... I have a chick I was told was a silkie but i questioned that because he has pink skin... turned out to be a sultan...

You need to know the background of the parents. With paints we are getting pink skin very often at hatch. Buffs very often hatch with pink skin, most of the time it darkens. Not knowing anything other than its an SG, not a lot can be said for what is going on.

I do have chochins, but no males, and the hens aren't lyaing yet. plus it hatched from a brown egg. I do no have any of the other breeds mentioned. Here is what I have that is laying/breeding age in that pen... turken male and female... silkie male and female... RIR female... buff orp female... serama male and female... black star female and that's about it

Could you post some pics of your birds?

I'm a geneticist, not a chicken geneticist, but ANY dominant single-gene trait can be lost from 100% homozygous in 2 out crossings.

A polygenetic trait is more complicated and depends on the specific trait, but you can lose it quickly as well.
