I will let @InterestingChickens answer that, but wow that seems pricey! Is that for hatching eggs? I would definitely want to visit them if possible or see more pictures of eggs and more of the birds up close for that price.Very odd, I've never really noticed my eggs changing colour at all, but then they are all the same colour so it not so noticeable.
Another question that I meant to put in the original post was this seller says this about them
English Cuckoo Marans ($130/doz) – available
Import line, dual-purpose, dark chocolate eggs, decent layer
Thats AUD.
Does this sound a reasonable price?
It seems a bit expensive but then they are quite rare here.
Oh, just noticed that you're in Australia to!
I have several Marans and their eggs definitely are much darker in the fall thru to spring and then they begin getting really light with dark speckles. I think they’re pretty both ways but these birds were a project batch so I got them cheap with no promises that eggs would be super dark. For $130/doz I would want those eggs to be at least a 7 or 8 on the Marans egg color chart. But if they are super rare in Australia, I’d say it depends most on what you really want! I’ve spent a lot on things I shouldn’t simply because I know I want it and I will be happy
