It's normal for a baby to start rejecting formula when they are weaning. Can you post a photo of her droppings? Are you giving vitamins? Lack of certain vitamins (I think B vit) can cause neurological issues.
Her poos are pretty perfect. Round solid brown balls all the time. Once in a while grey poo but I read that happens when they drink too much water.It's normal for a baby to start rejecting formula when they are weaning. Can you post a photo of her droppings?

She is a gorgeous little thing btw.
You can give her some Vit B. The lack of feathers around the head is also not normal. My pigeons dont like garlic oil on the seed, so she might not be keen on eating them. You can mix the Kaytee powder with a little bit of water to form a soft clay consistency. Then make small peasized balls and handfeed to her. To this you can add a pinch of vitamins. Just put the ball deep inside the beak over the tongue and she will swallow.
She looks fine to me, interested in what's going on around her. If she ever starts keeping the head upside down, then you might be dealing with paramyxovirus. But you got her from a breeder, so surely his pigeons must be in excellent health.
