So you hatched these birds from eggs you got from that breeder?
Even if the breeder has pictures of the birds from GFF being shipped to them, GFF could have had an oops and had a rooster or hen slip its pen and a cross could have happened. And GFF doesn't have TMA lines so those birds didn't come from GFF and the person he got his TMA birds from could have had an 'oops'. And the breeder you got the eggs from may have no way to know this, since maybe only his rooster is a cross that carries the blue egg gene but otherwise looks like an AC.
The thing is, there's no way that an AC that didn't at some point have something that lays blue eggs bred into it is laying blue eggs. The blue egg gene, as I said, came from a retrovirus from south america. If that hen is truly laying blue eggs, that means that at some point her ancestors were crossed out to another breed. Could have been one generation ago, could have been ten.
I would not breed and pass that on. Those eggs should never get hatched unless you want to market the chicks as something other than ayam cemani, because they're not ayam cemani, they're (possibly high percentage) crosses that lay blue eggs. If you want to sell them as fibro EEs, that's fine, that's what I sell my green egg laying AC crosses as. But it would be disingenuous for me to sell them as ACs, just as it would be disingenuous to sell a bird laying blue eggs as an AC because true ACs lay cream eggs and nothing else. It would be like selling a bird that looks like an ameraucana but lays brown eggs as a purebred ameraucana.
And I would check to see what color eggs the hens that are produced by your hens that lay cream eggs are too, because maybe your male also carries the blue egg gene, and if so he might be passing it on to his offspring. If he carries the blue egg gene I wouldn't be breeding him either.
my rooster has a little mulberry in his wallets but that's normal considering i haven't been able to breed it out yet.
Have you been working with these guys for a couple generations now? Because you said you haven't been able to breed the mulberry out, so does that mean you've been breeding for a couple generations? Just wondering because I'm working under the assumption that you hatched these birds directly from eggs you got from a breeder, not eggs that a past generation of your own birds produced.
And yes, mulberry is totally normal, but you always want to select the birds with the best fibro expression to be your breeders. So as little mulberry as possible. Selecting the best birds each generation will lead to improvement in fibro expression each year
