I am in desperate need of help. We have purchased an African grey that was still on formula. The breeder that we got him from told us that this is the way he gives his baby birds away, it also helps to create a bond between bird and owner. Unfortunately I only found out after we purchased Dixon that reputable breeders never sell birds like this. We purchased Dixon at the end of June and were told that he was 3 months then which would make him 5 months old now. No matter what I do I can't really get him to eat. We are trying the zupreem fruit and we have also tried the vegetable. The only thing he will eat without a problems is seeds, which I don't want to feed as a main food source. Fresh fruits and veggies are pretty much a write off with him,as he only eats a little bit on occasion. If anyone can give me some advise it would be greatly appreciated, as really don't want anything to happen to my little baby.
