I have one blue copper marans and she is lovely. She’s very sweet, will come visit me occasionally, and is super nice when held by me or my kids. She’s also my most vocal chicken, when she sees me coming near the coop she starts making dinosaur noises and it continues until they’ve all been let out for the day I swear she’s saying “it’s about time you got here” and then continuing to grumble about it for a few mins after being let out She is not hatchery stock however, I did get her from a breeder, and she’s my only Marans so I’m a small test case
I've had my black copper Maran since he was a day old. He started pecking at me last week, and yesterday gave his first crow. He's a bit skittish. I had a tiny runt Maran girl and she was sweet as could be but passed last week.
I have two Marans girls, a black copper and a lavender. I bought them as started pullets from a breeder, so they did not get a lot of handling when young. They are both sweet girls, curious but not overly friendly. They are towards the top of the pecking order but not the bosses. They do lay the most gorgeous eggs!
All of the Marans I have kept have been wonderful. I had a trio of BBS, the cockerel and pullets were all super friendly. Sadly lost two of them but the third is still a fave in the flock and even tried to jump on my lap when I sit down on the ground. My cuckoo Marans hens are also a joy, friendly social birds
