Here is the list that McMurray Hatchery sent me. (I specifically asked them) The following breeds may be feather sexed:
Araucana
Buff Orpington
Rhode Island Red (plus, they should have a darkish stripe down their heads)
Black Giant
Dark Cornish
Silver Laced Wyandottes
White rock
Buff Minorca
Single Comb Leghorn
Black Australorp
New Hampshire
Pearl Whites
According to the internet, there are other breeds that can be feather sexed, but again, it depends on if the parent birds where breed for fast or slow feathering.
