Here is info on Alley and question's.

She eat's all her food and drinks her water.

I let her drink some of that avi molt product.

She is starting to preen and when she got here she slept with her eye's open

now she sleep's normally. She is beak grinding the last few day's.

She is sooo cute when I put on the tv she is glued to it and she loves it do not worry I don't let her watch stuff with violence.

Question's

Is it a good sing if she preen's?

Is it good if she beak grind's?

Do you think that she is making good progress?

How big must her cage be.

I think that's about it and thanks to those how reply's. Kind regards bird boy

I'm happy to hear that she's doing better and making good progress
She's begins to preen and grind her beak, that's very good, all healthy birds do that.
About the cage size you will get different answers from different parts of the world.
That's what the Germans think:

They talk about a couple of IRN, because most of us don't keep parrots solitary.
When you think about the TV program she should watch, show her greetings from Duesseldorf.

All of it sounds positive to me. Make sure her cage is the biggest you can get. Indian ringnecks, and other Asiatic species, tend to have very long tails in comparison to other birds and so they need enough room to turn around and not damage it

Also, the sleeping with the eyes open thing may just be her eyelids. I noticed that my Echo had see through lids!

Congratulations, Alley does what all healthy birds do: preening to keep themselves clean and beak grinding is a sign of being content.
