Teaching a Flightless Bird to Fly

Ana isn't able to fly, so I'm trying to see if she can fly again. ------------------------------------------------------------------------------------------------------------------------------------------------------------ G'day! We're from Australia with 3 native cockatiels. Ana: Female, DOB 27/09/2020 Ana is a grey pearl cockatiel and she was bald as she was abused by her parents before she's 3 weeks old. She's timid and can be easily scared. Lemon: Female, DOB 29/10/2020 Lemon is a pied lutino cockatiel with grey pattern on the right wing. Lemon is naughty and lively. She can't leave people even for one moment, she is unable to stay in the cage for too long. Quishna: Male DOB 07/12/2020 Quishna is a pied lutino as well with grey pattern on the left wing. Quishna is the youngest one and he's smart and proud - never allow people to touch but he is gradually becoming the lead of the 3. We live as a family, eat and play together! ------------------------------------------------------------------------------------------------------------------------------------------------------------- #cockatiels #parrots #cute #kawaii #birds #pets #funny #birdies #angrybird #parront #28xtremes #chonk #chubb #borb #derpy #ChristmasParty #birdfamily
