It pretty much is saying that all GFF stock are mutts, yes. Pus, that's not how genetics work. If a bird is heterozygous for something and you breed it to another heterozygous bird, 25% of the offspring will be homozygous for whatever that trait is. So them being 'heterozygous' and the raven line being 'homozygous' makes no sense as an argument.
Plus they never say what they are supposed homozygous for, and as was discussed earlier, the fibro genes are not just one gene.
Also, there's this review about their stock that supposedly never throws culls:
"Great customer service. Very knowledgeable and understanding. Ordered 16 raven eggs, 7 were fertile, 4 hatched. Contacted about the low fertility and she said she would ship eggs if I paid shipping. Every time I brought up I got little response. I gave up, even after mailing a card with money. Birds have finally matured and not 1 has a black mouth. 1 rooster has quite a bit of mulberry. Plus side though I do love the inside of the eggs after babies hatched. I give a 4 star because the quality is better than anything else I have yet to get, but not quality I was hoping for. When I messaged regarding the mulberry, I got the response that that hasn't happened before. If I'm going to pay $150 for eggs I want the quality advertised. I will post pictures of the mulberry."
The inside of the egg thing she means is that 'pure' cemanis supposedly hatch with black dots on the inside of the shell, or at least that was going around a year or so ago. Mine do. And my friend's silkies do also, lol. So that is not in any way a determination of a 'pure' AC.
