Hello, I started breeding BBS bearded silkies from a variety of breeders hatched eggs. I started eliminating the blacks to focus on blue and splash. I hatched some chicks that looks a lovely light blue when hatched and grew to be blue but as adults have some light brown feathers. They are throwing occasional partridge chicks. I did have a lavender hen and am wondering if lavender x blue or splash can throw partridge? Thank you in advance!!!
