Sexing partridge

[Poodlemum]

What are the chances of creating sexable chicks from a partridge hen under solid male? Just wondering about the random genetic trivia y’all are so good at! Moms are BC1 Olive Eggers from a BCM dad and bred back to a BCM. I noticed some chicks have solid chipmunk stripes vs a dashed line

There are only two kinds of common sex links-- those that use the genetics of silver and gold, and those that use the barring gene. Neither applies here, and since they're mixes, they're not going to be autosexing either. I think you will have to wait until they are older to determine genders.
