Hugo is a great name for him! I love the meaning!
All the birds at the bird shop where I buy my birds, supplies, toys, food, etc., wean their birds to Roudybush pellets, so when Libby came home, that's what she was eating, along with fruits, veggies and other good stuff.
She was on the medium sized pellets, but I found out very quickly when I mixed some crumbles with the medium, that she loves the "crumbles" version, which is what my Parrotlet likes too. So until I used up the medium, there I was, every day, putting them in a baggy and "tenderizing" them into crumbles, so my baby would be happy!
So I guess it depends on the bird, but Libby has been on crumbles ever since and loves them -- she's a little pellet piggy!
As far as being fearless, Libby was shy at first, but once she figured out that good stuff to eat and play with comes from my hands, she'll eat anything I offer her. When she was a baby, she was fearful of new toys in her cage, but that's no problem now -- she attacks new toys with gusto! She's still wary of strangers in the house. She doesn't bite them, and will perch on their fingers okay, but leans waaayyy back away from them -- so funny!
BTW, my baby will be one year old on Feb. 27th! You're in for LOTS of fun him Hugo!
