Hi there, and welcome to the forum
I will move your post to the introduce yourself section, then there's will see your post easily and welcome you too
I am so sorry to hear of your loss, it's terrible. You are doing a great thing by taking care of your ate mothers African Grey :-)
Many people on here, myself included, as Glynn says, feed Animal Zone Pellets.
The main advantage this has over seed is that they provide a complete balanced diet - unlik seed mixes, where the birds can pick out the tastiest seeds, and discard the remainder. It is still a good dea to feed dily veg, cooked or raw, and occasional treats like nuts and fruit.
Have a look through the diet section, as there is so much valuable information there.
If you need anything further, lik where to get the pellets from, or any general information, post up, and someone Will be along to help
