The breeder, although recommended, was not one I would go back to again. She hasn't got back to me when I asked about the wing clip, and some of what she told me seems... well, lets just say the birds aren't exactly proving all she said about them (that they already eat fresh food and that they're well-handled: some of that might be due to them still settling it, but after a fortnight I would have hoped for them to be a bit happier in their old behaviours, such as eating the fresh food.)
Mercutio is cautious, which could have something to do with the fact he is a month younger than Malvolio, and could also be his natural disposition. He will climb on my hand for millet, but is still very hesitant and uncomfortable about that notion. I'm taking it very slow and careful, getting him used to me rather than rushing in, so that hopefully he can trust me as time goes on.
As soon as he's confident, I'll bob him gently up and down to get his wings flapping.
He does try to fly in the cage sometimes, bless him, but honestly it's a bit of a worry. He seems to hit the floor with a fairly hard bump.
Thank you for your advice. I'll let you know how he's going!
