The D’Anver in my icon was hatched singly by a broody, the broody then got taken by a fox when the chick was three weeks old. What a nightmare that chick was, she was friendly up until her last moments but would not leave me alone. She constantly wanted to sit on me and clean me or sleep in my pocket. I remember in the first few weeks when she realised I was her only “friend”, she’d cheep and cheep and cheep, the more you ignore them, the louder it gets. I had to take her everywhere with me, in my pocket or in a carrier in my backpack or on my shoulder. I hatched her three Welsummer when she was nine weeks old, she hated them and perched as far away as possible from them and still chirped like a small chick. At fifteen weeks old (when I dispatched my whole flock) she still chirped and cuddled me as she couldn’t understand the difference between me and chicken, if that makes sense? So whilst it is cute and does make them friendly, they’re dysfunctional as a chicken, it is unnecessary to raise a single chick when there’s other options there.
I completely recommend either getting two to three pullets or buying 1 or 2 laying hens 2nd hand. If your girls go broody, you could always allow them to hatch eggs to add to your flock.
