I think Cochin is a strong likelihood because of the feet feathering and the shape of the head and the large flesh spot around the eye...typical bantam Cochin look. And Cochin comes in standard and bantam size, but even so, if you breed a small bird to a large bird you tend to get varying sizes of birds in between.
However, there is a lot of look in the birds that is not Cochin. The body type is different and they have crests.
The cresting suggests either Cream Crested Legbar or some other partially crested bird, or it could be, and I think is most likely, some Silkie thrown in too as one bird looks like it might have 5 toes. If you see some with 5 toes, that would make Silkie almost a certainty, although Dorking a long shot possibility.
I think you have mixes of mixes. There's a lot of genes floating around in the looks.
If I had to take a somewhat educated guess, and this is a guess, I'd say Bantam Cochin, Crested Legbar, Silkie, and something else too.
