View attachment 1735498 This is my bigger little one at 7 weeks. My little pullet has sloping sides on her comb, but I saw defined ridges on your Isabel, like it was made of play dough and someone pinched it, you know? It looks much more defined than the comb on my pullets, even if it's not very tall like on your chocolate one.
The red light in your photos throws me off, so I can't really tell her comb color. Mine has been the same very pale pink with black specks since we got her; it's never been yellow, but maybe that's a lavender vs. Isabel thing.
Also, your Isabel has very bright red/hot pink wattles in pictures 1 and 6, especially compared to the comb. They're bigger than the wattles on my pullets, but not by a ton. My pullets' wattles are the same pale pink as their combs.
This is my first experience with Orpingtons, and I got two pullets from a breeder who was extremely confident about their sexes. I hope my pictures can help you figure out what your little Orps are. I'm certainly no expert, though.
