Hi all im a new member so I’m very happy to have found this forum. I’ll be getting my African grey in two weeks and I’m having questions regarding their diet. I know the food they can and can’t eat. I also know their diet consists of pellets veggies, moderate nuts , moderate seeds and fruits. I know it’s 75% of pellets 20-25% of veggies and fruits and 5% of treats(nuts,seeds). However, I’m wondering how many times a day I should give her veggies and how many fruits she can eat. Can she eat one entire banana or should I just cut in half and give her the half? How many sun flower needs should I give her and how many almonds ? I guess it’s one almond a day? I read I could give her a plate of veggies and fruits in the morning and one hour before going to sleep then give her treats throughout the day. Is this correct? Thanks a lot and sorry for asking lots of questions but I want to know how to feed her so I don’t make mistakes.
