Awwww
I'm so sorry. Seemed like you really had your heart set on that bird. I hand raised a little ringneck once.. he was my special sweet boy, one of the family. Wouldn't harm a fly. But when he was about 7 months old, his eyes starting dilating and then suddenly not dilated. They'd do it all day... he then suddenly turned on everyone in my family, even my daughter who he loved, and he started attacking his mate (full on attacking.. if we left her with him she'd have been killed). He was apparently fine and nothing was wrong.. so we decided he must've had a screw loose in his head. So we had to sell him.. i didn't want my precious boy sitting there in a cage all alone... no cuddles from people or birds.
One person called me offering $200 for him. He was just a normal blue! O.O But they kept avoiding my questions about what experience they had with birds etc. All they'd tell me is "I really want him."
Then another lady called from a City about 10 hours drive from me, telling me everything about herself, where my boy Howl would be, what she would feed him, that she'd send me updates regularly, and that she'd keep his name, because that's who he is. And she was just plain lovely! I was going to sell him to her for just $20 because she was a tad tight on money... but she had fallen so in love with him that when she put the $20 into my account.. she paid me $110 O.O .. She demanded I keep it and got grouchy when i insisted i refund her. so to keep her happy I kept it haha. I now have about 30 photos of him with her. s soon as she picked my Howl up from the airport, she got into her car, opened his box and let him out.. he hopped straight onto her shoulder and cuddled into her neck... He hasn't bitten her yet.. and she'd had him for about 8 months already! He is now her pet and he loves her house-mates too. She takes him EVERYWHERE with her on a leash and he is back to his normal sweet (but cheeky too) self. I am SO GLAD i sold him to her.. it's so fantastic to see my troubled insane bird back to normal and loving cuddles again! *goes all warm and squishy inside* Anywho.. sort of went off the subject there
But it just shows, if someone who's selling a 'precious' bird of theirs is more interested in the money.. then the bird can't be that precious to them.
But don't give up yet! If you are persistent (in a polite way of course
) she may see how much you really do love her bird, and perhaps you could offer her a price, reinforced with the knowledge that the bird would be going to a loving forever home with someone who knows how to care for birds, since you already own some. If it doesn't work out however, I'm sure you will find another bird that's perfect for you. I know, it's not THAT bird, but other special family birdy members can and do come along.
I hope you find a good little bird somewhere ells. Why wouldn't she want you. You told her your birds so she knows you have experience and that you care!?!? I hope every thing works out for you!
