We do get birds in that have less problems, I would say read up (there is tons of info on here) on first the changes you might need to make in your home to be able to offer a bird a safe home, No teflon pans, no air fresheners,perfume and chemical cleaners, Do you have small children that might leave doors open ? dogs or cats that might scare or jump up at the bird, are you home during the day etc.
We as a rescue do not clip wings, do not like birds being the only bird in your home especially if you are out a lot.
We have a duty of care both to the birds and to the people that hand their birds into us, to ensure the bird gets the very best of care.
You can visit www.parrotcareinfoforum.com to talk to people that already have birds from us and get information on how to become a foster carer.
