All are pullets!! I doubt this truly was straight run, likely a mislabeled layers assortment!!
1-likely a Sapphire Gem. Potentially could be a Blue Orpington or Andalusian
2-Is is pure white? Does it have any dark markings on hackles? If dark markings I'm guessing Delaware
3-appears to be another Easter Egger but Cream Legbar-derived
4-Dark Brahma
5-from what I can see it's an Isabella Leghorn. Hoover's did carry them over the summer but they're now mysteriously gone from their website. Is she solid lavender or does she have some markings/muted warm colors?
