Hi, I started hatching eggs with my brinsea incubator last summer and hatched 4 out of the 5 eggs. I now have 4 cuckoo marans who are 12 weeks and I was wondering if any body could sex them? Any help would be great, thanks! (from my limited knowledge I think there may be 3 cockerels and a hen but I do not claim to have any extensive knowledge!) I know the picture is not top quality but any help would be great! P.S they are about to be moved into the much larger hen house with my current flock.
