My FBCM are excellent layers.... all of them lay between 5/6 eggs weekly...Marans are good birds. They're pretty inconsistent layers though. Used to have a French Black Copper Marans hen, & a couple American Cuckoo Marans.
Spelling is Ameraucana. They're technically just EEs with a standard.
Feathered legs depends on where they came from.
But I'm starting to realized that European lines can be quite different from American lines...
