So Zuri more or less lost another gram today compared to yesterday, which isn't a huge loss I'll concede.
He's still very alert, wants to move, chews up paper like crazy - given he's maintaining a nice activity level, I try not to worry too much.
When we had him out this afternoon, I took Shade out as well for a bit. Both pinned their eyes excitedly at each other. Then I figured why not get a long strand of millet and get them to nibble on their respective ends. Shade rarely turns down food (as in I don't think she's ever done so..) and Zuri generally wants whatever another bird has to eat. And while Zuri showed no interest in the millet at first, the moment Shade started to eat it, he overcame whatever issues he had and plowed through the end closer to him. While Shade was a very neat eater, going for one grain at the time, Zuri was pulling quite a few in his beak at once. Of course, he didn't eat all of them, but he would munch at whatever remained in his beak.
A good sign - with the week-end at our door, I'll be able to do more of that throughout the day.
