Hello Gail and welcome to the family, so glad you could join us and we look forward to hearing more about you and Angel.
How sad that he was kept in conditions like that, no wonder he is messed up, how could anyone leave him covered up most of the day and smoke weed around him but he has a new home now and I am sure he will blossom from your attention.
He needs a balanced diet full of veggies, fruits, some seeds, nuts, legumes and some pellets but it looks like he has a serious plucking problem that you may never cure him of but I know you will do everything in your power to help him stop.
Please take a little time and read thru the many threads for lots of useful information and ask questions I know you have. We will do our best to get you some answers and help you in any way we can.
Thanks for sharing some pictures of Angel in another thread, he is handsome even though he is missing a lot of feathers but then real beauty is on the inside.
If you haven't already please take him in to see an avian vet for a complete workup, he probably needs that badly and he/she can provide some advice on what he may need to return to full health.
