Love the pic of Biscuit! I know you are not breeding Dels, but if you were, I see a couple that would be culls due to their too dark, and frankly, too solid-colored, hackles (though Dels do change quite a bit as they grow) They should have barring, which really looks more like dots on those skinny hackle feathers. Georgie has too-dark hackles herself and I see another reason that I probably shouldn't hatch her babies anymore. She tends to throw that dark coloring more often than not. But, you have yourself some sweet, friendly girls there, Nick, and they should be great layers!
