Thank you for posting these links. I have not been to either of those websites in years. I’m happy to see that Garrie Landry went back to breeding. It’s always sad to see such an expert quit.You can go over to the Finch Forum for more detailed tips on sexing and breeding them.
Cindy Fox Moore is very good with them. So is Charlie Moorecraft. Both breeders are on Facebook as well, as is Garrie Landy.

@ColtHandorf what was/is your username over on the Finchforum?
How many is several? I wouldn’t be surprised if they all missed the darker beak.The consensus is CHESTNUT FLANKED WHITE HEN. said by several people.
It does sound like whether or not it’s a female, you shouldn’t have too much problem with unwanted extra clutches. (Unless they get their act together.)
