I found out that Coco loves hating gold. I know it's controversial, but really, he does. He is now back on track and seems to be happy again

He's not hating it. That's how cockatiels play: they chew on things. They especially like shiny things. He's just doing what cockatiels do best!

IKR!? I attached the chain to his cage so he can have fun with it and not be bored. Pip looks at Coco like: "You weird bird, you are a disgrace to the cockatiel family", and then starts doing it himself!!!

Maybe pip is just jealous.

Lucy likes to play with my seashells. She'll chew on them, then pick them up, and walk away with them. Not sure what she's thinking when she walks away with them.

They have such big personalities, for little birds.

Adorable!! He looks like a charm.

I think he loves it! When you try to pull it away from him he hangs on and pulls back trying to keep it. Just don't leave him alone with it unsupervised. It's long enough to get tangled around his neck and we don't want any accidents.

It looks like life is wonderful for everybody again - the birds are happy and healthy and they enjoy being with you.

Yes, they are . But I'm still concerned for Coco's health; he hasn't drinked water on his own. I tried giving him water again and drank from my hand, but not from the bowl. What could i do?

He must be drinking water when you're not looking. If he wasn't doing this he'd be dead by now! But you can always provide a shallow bowl of water that's big enough for him to take a bath in. All my chicks learn to drink water by sticking their beak in the water while they're wading, and it's fun to watch them play in the water.

The problem is that my cage has four tiny little doors and i cant fit anything in there

Can you cut the doors in any way?
