I loved your story. Yes this is a great place to find out about stuff - important & otherwise
I have had to trim claws myself. It’s not too difficult but a 2nd person is necessary. There's a thread by Peanut's mom with a video on nail clipping. My accomplice wore gardening gloves & held the bird in a hand towel - boy those delicate little feet sure can hide! I took only a very small amount off at a time - the nails are sensitive & will bleed too if you take more than 1/16'' off - if they are really long you'll have to do it again in a week or two, as the inside part will recede.
There have been some pretty fun threads on harnesses or bird diapers with a leash. It would be great if your bird could go outside with you to visit the garden.
Good luck with the little guy - where are the pics of him & all his stuff?
PS - Tallahassee is a great name - I've always likes it LOL
