1: appears it could be a lavender Orpington: lavender/silver color, very large (6+lbs?), brown eggs, silver legs, 4 toes, dark beak and very red single comb, very fluffy.
2: Appears it could be a leghorn?: white with a tiny speckles of black, smaller sized (maybe 3lbs?), yellow legs, 4 toes, large white eggs, single floppy comb, yellow beak.
3: at a loss on this one...sultan, Easter Egger?: pure white, walnut comb, white legs with light feathering on shank and a little on feet, 5 toes, lavender/silver skin on the outside/underside of eyes, silver/white beak, white puffy feather crest, med size (about 3lbs?)... Sultan, right? But she lays light green eggs almost every day! Maybe an Ameraucana/sultan mix?
Sorry for the terrible pictures but any help would be greatly appreciated.
