I've read that about smokey as well Sonoran. I'm just having a hard time figuring this one out. I'm sure the next mating will give me some answers, but thought I'd share for insight and education in case anyone else sees this.
It isn't blue..I'm certain of that. The feather shafts are white on the outside like lavenders. They have no dark lacing and the color is kind of a flat matt slate shade in person.
I've ruled out blue based on how the birds originated.
One breeding was from lav roo to pure black hens - produced all black offspring. If blue was present in the lav bird, I should have seen blue and black offspring, however they were only black.
I took those black offspring and mated siblings - some are this slate color, as well as lavender and black chicks.
I also took black offspring back to the original lav roo and got the same - some slate, some lavender and some black.
The first bird I pictured has a bit of a chocolate appearance when seen in person. This is in comparison to a bird I am looking at in the 21st Century Poultry Breeding book on page 111. Although I don't think it could be that either.
I don't think it can be dun/khaki either, but looking for insight on possibilities. Or is this the typical expression of some lavender birds, which are culled out due to dark color?
