Sorry it took me so long to reply.
Thank you to everyone.
Sparky could fly when we got her, but she would fly
very infrequently. She was a crazy, lopsided flier because of her left wing and she wouldn’t land nicely- she'd crash land almost every time. For some unknown reason, her left wing started growing out. I've noticed she now flies to get where she wants to go. She isn't zooming around like Junior, but if she wants to go somewhere she'll fly there. She loves Afie's cage, when she's out and not on a person, she's on Afie's cage (as long as Afie's not there). And Afie's cage is in the living room, so Afie's cage is like a playstand to her. Most of her flying she does if she wants to go to Afie's cage and I don't take her there. She occasionally will fly to a person, but it's not a common occurrence. I noticed when her left wing first starting growing out, she'd flap and just somehow land on Afie's cage. Now she makes a half loop to get a good angle to land. So she is definitely learning, but she doesn't like to fly anywhere but there, meaning she isn't so good about flying through the rest of the house. It was actually my fault she got scared. I was in the dining room with her and Yoshi was on the table, Yoshi came too close to her because he was curious (he isn't aggressive torwards other birds. just curious), but Sparky is terrified of him. So she saw him and took off. I'm not used to having flighted birds, especially not a flighted bird who is still an unsteady flier. Junior is also fully flighted, but she's old and doesn't fly that much. Also she knows the lay out very well and is an excellent flier, she darts around with ease. Afie is lightly clipped, but she doesn't fly. Yoshi wasn't allowed to fledge, so he's not a good flier, but he's growing out his wings. What are some other tips on keeping her safe. I know windows are an issue, so I'm going to cover all the windows in the rooms she has access to. But the kitchen window can't be covered and the wingdow is there. I'll lock her up when we're cooking, but there's no door to the kitchen meaning she could go in there if she's out. I heard putting post-it notes on the window shatters the illusion that it's open space. Is that true? Any help would be greatly appreciated. I'm just trying to keep her safe. There's no standing water, (bathroom doors are closed and toliet seats are down), and no fans for her to get injured in.
