many ppl think of them as the same, just like ameraucanas and EEs, but they are actually different breeds. :) I understand. Love their colors which is why we are keeping one of the roos. Would keep them both, but I have way too many roos as it is.
Looks like probably a booted bantam. Very similar to d'uccle but without the beard. I ended up with a booted bantam and a d'uccle from TSC. Both are sweet birds, but both are roos. We are keeping the d'uccle. Here's a link that may help: http://www.belgianduccle.org/belgian-duccles.html
I am new to marans, but I love them so far! I have blue birchen marans juveniles that are about 4 months old, and I have some blue copper marans chicks. My blue birchen marans are supposed to be from the Greenfire Farms lines. If the blue coppers are good quality, can you breed birchen to copper...
