Hello guys,
Sorry about the late reply's and i really do appreciate the comments its horrible to lose a bird, its was very hard for my mother anyways still is.
Apparently Zinc and Led Toxic poisoning. Along with the calcium deficiency. The thing is according to the vet and insurance etc this takes a long time to happen. We had Finbar just over a month. So according to the vet he wasn't taking care of at a young age. We got him from a pet shop near where we live, there was a lot of different types of animals and birds there, you'd of thought it was a decent shop obviously not.
We are going to get another parrot, in fact we already put deposit down. Hes going to be called bandit and he is from a proper breeder we get him in May. We are not 'just' replacing Finbar, he was an amazing parrot and we do miss him a lot. Feels so weird not having him around.
Again thanks for all the kind comments, its very much appreciated.
Sean
