Looks like two cockerels and a pullet to me. Two with much larger combs. I would try to get a picture where their crest is not wet, so that we can see if their crest is "poofy", "swept back", or if there are "streamers".
When they hatch, they should have beards (see pic to left on my profile - that chick is about 1-2 weeks old). As far as gender, I have had no luck! Some people say by number of rows in comb +/- getting tail feathers in more quickly..
I have light, light partridge hatch from my birds. They are all blue partridge; initially I thought porcelain as well, but genetically I don't think that is possible. After getting her adult feathers in, it came to me - since breeding blue x blue can give you splash, that must be what it is...
