Bald spots on chick

[molly1chickens]

I’ve noticed my (almost) 2 week old Orpington chick has always had bald patches on her neck, under her wings and a bit on its back. None of the other chicks have the same problem- is it normal or is something wrong? Attached pics:

That can be normal as some chicks grow faster that they can grow in feathers.
