Thanks. This is very interesting to me, since I know little about the genetics or origins of this bird. So the feathered legs must come from the Wheaton Marans, but the Wheaton likely got them from some other cross. So dumb question, but is there an original chicken somewhere? I know you can make all kinds of crosses and there are mutations that happen, but what are the early origins of this bird?According to the French Standard a Marans has to lay at least a number 4 egg consistently to be called a Marans... and then you get into colors............anyways most all of the current Types breed true and the reason this kind does not is because of the limited stock in the US and that they only recently were developed. https://www.backyardchickens.com/content/type/61/id/6689581/ If you replace the Leghorn in this chart with Wheaton Marans and the Barred Plymouth with plain Cuckoo Marans you are suposed to get Golden Cuckoo Marans and replace the Wheatons with Birchen the you will get Silver Cuckoo. This is my understandingI've been skimming/searching this thread and noticed that Golden Cuckoo Marans don't seem to breed true. Just looking at the first post, you can get [COLOR=333333]Salmons, Silver cuckoos, blacks, wheatons marans roos. I only have 1 hen and 8 roos. The roos all look different, but the female (which I have nothing to compare it to) has the barred trait. Now due to the sex-linked barred gene, the females always look barred, right? Regarding the roos, you got a whole mess of genetics to work out. [/COLOR]My other question follows up on this: so since this breed does not breed true, is it really a breed? I don't have APA standards book yet, but I'm guessing they aren't listed under the marans section yet.
