I don't like my photos circling too much, certainly not outside BYC (plus, I'm not sure my birds are what you're looking for?), but good luck securing some photos, and good luck on your presentation :)
If they were rotting, I'd consider leaving the healthy roots and plants to air dry for a few days. The soil looks very moist, good thing you got them out. Don't water for a while!
It's not even funny at this point. The photo of that lovebird might've sent me over the edge (I've always loved lovebirds). The need for another parrot is too much
I don't think it would mind a repot, but it doesn't seem to be in a dire need of one. If it doesn't have holes, I would repot it. Makes it easier for you to care for it, and the plant gets more room in return
Looks like sumpervivum to me! Gorgeous little plant. Treat it like you would most succulents. Sun, loose soil (not too loose), and not too frequent of a watering schedule. Does the tea pot (lovely pot, by the way) have drainage holes? If not, you'll need to be very mindful with watering
That's rather ridiculous. Was it even hand fed? A wild type cockatiel that was not hand raised (not that I particularly love the concept of hand raising, but it does usually increase the price a bit) should not be costing 368 Euro
