Thank you so much! So with this wing-patch, if I was to breed Willow, my Lavender (thank you for helping me figure out the best term) OEGB pullet ~with possible wing-patch~ with my Mottled OEGB cockerel, that defect will only show in lavlav?Recessive is what is carried, yes.
Lavender is recessive.
Lav+Lav+ means the bird is not lavender. Lav+lav means the bird is not lavender but it carries the gene. lavlav means the bird is lavender.
Yes there is a gene (wing-patch) that causes poor feather quality and is linked to lavender.
I assume it is blue. People do not always know the difference, but blue is blue. Self-blue is a horrible term that only confuses people.
