Baby Budgie: Day 28

Zazu is now 4 weeks old. I have had him for 2 weeks. He is doing very well. He is eating adult food and foraging between formula feedings. I am still feeding him 4 times a day, but the 2 middle feedings are not as big anymore. I feel keeping him well fed with formula will encourage him to do more foraging on his own. So far this is working.
He is so much quieter when he has food in his mouth. He has become a little more independent of me. He is not as beggy all the time regardless if he is hungry or not. I am attempting to expose him to as many different foods as possible, including a little of whatever I am eating. I stopped scattering seeds on the floor and it in a bowl. When he is grown up, he will need to search a bowl out for food.

I have exposed him to seed mix, nutriberries, birdie bread, part of a mash mix (legume/grain/seed mix but no vegetables yet), and whole pieces of dark leafy greens from my patio garden. I should start adding mashed vegetables to his mash mix as well as showing him what spray millet is. I want to get some cooked varieties of food as well. This way as an adult, he won't be too picky about his foods.

He has been testing his wings today as well. I was so pleased to get a shot of his wings open while he was flapping. He is still not ready to fly or attempt to fly.
I wonder if this will be the week he learns to fly. He will probably switch to 3 times a day this week as well.
