We bought 4 day-old chicks as cuckoo marans. One has a lot of speckling, and another one has quite developed comb and wattle at only 17 weeks old and doing a lot of nesting activities. Can she really be a cuckoo maran? They lay at 6-7 months old, from what I've read. See how underdeveloped the speckled one's comb and wattle is? Is she a different breed like barred rock? I'm having trouble loading the pictures.
