I have silkie chicks at home and the last two definitely look like silkies, but they all look like mixes to me. I have Silkie/Serama mix and his feathers were different to. Actually my picture < is of him. So I'd definitely say they are a silkie mix, especially with having the black feathered legs and 5 toes. The last two look more like my silkie chicks, just not as fluffy, granted mine are now 2 wks old now. But I'd say they are mix too, second to last looks like a partridge mix, and the last looks like a blue mix. If you go on my website you can see pictures of my silkie chicks after they hatched. If you'd like some silkies I actually need to get rid of mine and I have plenty of chicks to choose from. But either way your chicks are very cute and I love my mix. I think he's beautiful. It's so neat seeing the different features in him. He has the top feathers of a Serama, with the under feathers of a Silkie, with feathered feet and 5 toes, he has the comb and waddles of a Serama, with the body more like a silkie. He is adorable and very, very sweet.
