There's a gene called Duplex that does funny things to combs too. IIRC buttercup is an example of Duplex comb. Houdans, polish la fleches have it too- the double 'spikes'. So it can be involved in funky combs but from my crosses mixes it seems just the presence of crest itself does strange things to combs.
. I have a batch going in bator Feb3rd-ish of other birds but plan on putting in a bunch of my OE's If I can spare them between orders...Maybe 6?? I love my straight comb OE girls-they look just like black Ameraucanas except with slightly feathered shanks-afterall they are egg layers, so thats a plus plus whether they lay OE eggs or not
