the curious case of a chick with two dads ( a head scratcher for sure)

[JedJackson]

I will have to disagree here. Isn’t the fibro gene dominant? Shaggy would have a lot more indications that she carried it (and some hints to where she got it from!) if she did carry it. And for it to pop up when crossed with a white-skinned bird who’s got no fibro in his heritage…it’s about as likely as some crazy genetic mishap what wound up making a chick with two fathers.

So what's your answer? Two fathers for one chicken? That seems far more unlikely to me. In fact, it is impossible.

As I said, I’m not sure.

Do you have a link to that thread?

To my gyspyfaced one? Give me a moment, it's from like a year ago

Its actually not. Usually they form chimeras though

Hoewever I'm not sure if the rest of her was dark colored. I lost her to a rooster when she was brooding this spring. But her adopted daughter has a dark face too... I wonder if my male is throwing it. I'll have to check

There is a dominant gene for light skin, and I've read that it blocks the fibro from expressing. So I think a chicken could have the fibro gene, and the dominant gene for light skin, and not look like they have fibro at all, but still be able to pass it to their chicks (who would only show it if they get the recessive gene that allows dark skin to show.)

Considering the comb and the crest, I think the Polish rooster must be the father, and Shaggy (the mother) probably is the source of the fibro.

The gene for light/dark skin is sex-linked, so a pullet gets it from her father but not her mother-- and Polish are supposed to have slate legs, which would mean they have the recessive gene allowing dark skin.

A possible test: if Shaggy (the mother) is crossed to another rooster with dark legs (blue/slate or green/willow), that cross might produce more daughters with dark skin. Sons would probably have light skin, because Shaggy herself has light skin.

Is it possible she had two dads?
I’ve heard it can happen in litters of mammals - but I don’t know about chickens.

It happens in snakes too.

It's semi dominant, & can be sex linked.

Sex linking with fibro birds works with breeding a Fibro rooster to a none fibro hen. Resulting in females with black skin, & males with white.

Silkies are genetically white skinned birds with the Fibro genes, just to put that out there. I breed silkies.

I believe it's possible for a chicken to have two fathers. In rare cases.

Have handsome or Beetlejuice been bred again? If so, what offspring did they produce? We’re you able to notate their genes based on what they threw?
