They look like they would do great in warmer climates, maybe retaining some of the Penedescena genes?
The Mediterranean shape has come to dominate here, through natural selection, and the Penedesenca genes are widespread. These hens are 2nd/3rd gen cross-breeds with about 25% P I think.
Specifically, Aberglasny is Idris' daughter, and Idris' mother could have been a SFH, a SDW or one of 3 hybrids in that clutch of eggs; A's and I's dads could have been any of those living here at the time; Idris' comb and egg and shank colour suggested Amadeo; he was an Isabella leghorn. And she does lay one of the lightest colour eggs here, so that also suggests Amadeo was her granddad. If so, Aberglasny is a bit of a Heinz (57 varieties) with relatively little P.
Sully is Ystrad's daughter; Y's mother was Neath, who was SFH x SDW, father again unknown in both generations. Sully lays a large medium brown egg, darker than her mum's, and suggesting more P heritage than A, but the SDW grandmother lays a relatively dark brown egg and must be the source of the yellow in S's (green) legs, so the picture is muddied there too.
Anyway, I think A and S's Penedesenca genes have come from the male side (where they're ubiquitous), and they must make up at least 25%, whether visible or not. Killay is P x Araucana, Fforest is P x SFH, Gwynedd and Tintern are both probably 75% Penedesenca (pure P mums, hybrid P dads).
(The other males, E, H and N, are A and S's generation, so can be left out here.)
If anyone wants to comment on these speculations, do please pipe up. Chicken genetics is like spaghetti in my brain.
