If anyone can give me advice I would greatly appreciate it! Sorry in advance for the novel but the more info can give someone more of an idea as to why this is happening!
Here's a bit of a background of Marley : Female budgie , 20months old, got her as a hand fed 4weeks old baby.
Marley has always been shy and skittish but loves preening everyone! In august she started regurgitating seeds so I brought her to the vet. She had a virus, vitamin A deficiency and slightly underweight due to bad seed only diet. After that she went on 2 rounds of antibiotics (4units of Chlor palm 2x a day for 3weeks...twice) The vet told me I would be better off switching to pellets since she was always so picky with veggies/fruits. Tried that but after 6 weeks of slow integration in her seeds she just wouldn't take them and was obviously starving I decided to stop everything and get her back on a higher quality of seeds diet, kale when she feels like eating it and vitamin supplements in her water. Now she's eating normally again but I understand the stress of the last 3months affected her.
She's always been a sweet bird, still is, she talks a lot and sings but lately she wont even get out of her cage without biting me (HARD!) She takes off skin every time, he tail feathers flair out when she attacks my fingers, arms, clothes. It takes about 5-10min of me talking to her and her attacking me before getting out of her cage. Then she's her normal sweet self!
I've tried reinforcing that if she bites she stays in the cage but then she never gets out and I don't want her to become untamed. How can I get her back to her sweet self that's scared of thumbs and just jumps out on my palm?
