I really am sorry that you lost Coquette. Thank you for taking another bird into your home. There is a section of the forum for birds with special needs e.g. foot amputations, and they can give lots of advice on setting up a suitable cage and helping his confidence. Click on this link -->
Special Needs Crossing
I understand that you are grieving your lost bird, but in the gentlest possible way, I'd like to point out that you are projecting your grief onto this very different situation. You are making a lot of assumptions about Kamara,
@hrafn and the adoption process they went through, and I don't think it's helpful for you or kind to hrafn. Knowing something of hrafn's experience here and the condition that Kamara was found in, I don't think it's the case that someone is out there still desperately searching for her. Kamara herself has damage to her feet and spent a long time in a shelter. The shelter would have advertised her and people looking for their lost bird, vets and others involved in reuniting birds with their humans usually keep an eye on shelter listings. No one came forward to claim her.
Happily, Kamara found a home where she is loved and taken care of, with someone who is gentle and patient with her.
