Help identifying our mixed brood

[Dgrif5]

Hi, firstly I'd like to apologise if the photo quality if insufficient, they are quite skittish and these are the best photos I managed to take of them (out of dozens).

About two months ago our broody hen hatched a mixed set of eggs of several breeds. Some were Brown Leghorn, some were Vorwerk, and several were unknown. From what hatched we appear to have 3 Leghorns, 2 Vorwerks, and 2 of unknown breed. Any help in identifying the breed of the two mystery hens would be greatly appreciated!
Also, if anyone has a good guess as to the gender of any of them, that would also be very helpful. We currently think that we have one Leghorn Cockerel and one Vorwerk Cockerel, but we're not entirely sure and don't want to make any snap judgements.

I'll try to update with better photos if I manage to get any. Thanks for your time!

I see a trio of Buff somethings; I assume those are your Leghorns? A pair of Vorwerk, and then the two odd ones out appear to be pullets, so your right on the cockerel front. I see little crests on those two; do you happen to know the varieties available from where you got your eggs, and if there is a possibility of them being mixes?

Did you get the eggs from a local breeder or hatchery? If it is a local breeder, maybe you could ask what breeds they raise, and guess from there. If a hatchery, which one? Perhaps they have a list of breeds that could help narrow it down.

I'm kind of drawing a blank on the two unknowns. Maybe Swedish flower hens?

You have the genders correct I believe.

Is that black one a Black Swedish?

Thank you very much for all the replies! I really appreciate the help in confirming the genders, though we were still vainly hoping we were somehow mistaken about the cockerels...
As for the mystery hens, we we're given a selection of eggs by a friend of ours who keeps a large variety of hens of all kinds. It could be a Black Rock as he does have several, but it doesn't look much like other Black Rock chicks I've seen, especially with the tuft, so I assume it's some strange cross of some kind. As for the other young hen, we have absolutely no idea i'm afraid.
