They are quite likely to be Runners crossed with something else. Their colours are really beautiful - especially that one with the eye stripe standing on the right in the first pic - that one is a little stunner.
All of them obviously have either one or two blue genes. The one on the far left in the top pic seems to also have a dose of two of the Light Phase gene (like a Saxony). Although she looks a bit like a Buff Orpington she is not, because she has eye stripes (Buff Orps do not, as they have the Dusky Mallard gene which removes eye stripes). However she may have one Dusky gene plus Light Phase - not sure!! Anyway, I think there is some Saxony colouring involved, possibly. Either way, their appearance points to a mix, but a very beautiful one!
I hope you are enjoying them, even though they don't have pom-poms :)
