@ColtHandorf that entrance was awesome

OP ... I am not as experienced, but I see some stress barring in her feathers. Those little lines. That might have been what she was talking about?
According to what I read in another thread, in other colors stress barring is serious because it shows times the feathers stopped growing. But in Lavenders the same gene(s) that causes feather shredding can also cause the stress barring, so it usually has no health implications. The shredding often shows up later in pullets.
That breeder's choice photogenic hen also has shredding, it's in her saddle area. And as ColtHandorf said, both of those example progeny have it.
I'm glad you made this thread because I wanted to talk about this too. I've been scouring the internet for a source of Lav English Orps that don't have shredding and I can't find one. All the best and most recommended breeders, upon blowing up their pics, it's right there.
I have two Mottled English Lavender 3 month olds that are just recently showing the shredding (ugh!) and I thought I was going to have to replace them. But if there's not better to be found I guess I'll just breed it out with the blacks.
The way the breeder turned it back on you was, IMO, really wrong. She must not be used to people calling her on the quality of her birds. I think it's quite fine to sell birds that are "in progress" as long as you disclose to the customer what faults you are seeing. And she surely has seen a lot of this in her own hatches.
