Rescued Rainbow Lorikeet - HELP!!!

Question
Hello -
We recently took in a foster Rainbow Lorikeet.  He/She has suffered some sort of animal attack (assumed cat) although he has been treated and in a rescue for over a month he still has some nasty abrasions on his neck and chest, that occasionally weep.
Naturally he is still missing a good portion of his feathers around his neck, chest, crop area.

I have two questions - 1st one is, after he eats his crop/cheek area seems swollen or enlarged.  It may be normal - but since he doesn't have many feathers there its very noticeable. Do they hold food in their crops/cheeks ??  Is that normal?

2nd question - Is there anything i can give him and or spray on him to aid him in healing and or encourage feather regrowth?  I am growing very attached to the little guy and It breaks my heart that his chest it still so open and sore looking.  Like when my kids get a booboo.. i want to fix him! ( :

He came to us as we have a good amount of bird experience,(parrot/conure) however we are new to Lories, so any advise would be greatly appreciated.  I am currently working from home, so i am able to spend a good amount of time with him.  He is healthy and happy besides his neck, dances, eats and chatters all day.  

THANK YOU SO MUCH FOR ALL YOU DO IN HELPING ANIMALS!!!  I GREATLY APPRECIATE ANY INFO YOU CAN GIVE!

--  I'm sorry for the delay in getting back to you.  I'm very concerned about the 'rescue' place that had this bird.  Did they administer appropriate antibiotic regimen?  IF they did, you shouldn't be seeing what you're seeing.

I hate to say this, but we see a LOT of so called 'rescues' that have no idea what that means.  It means that each and every intake (bird) gets a vet visit within 3 to 5 days of intake.

It means that whatever that animal needs in the way of medical care is provided for, no expense spared and this is what we maintain as long as the animal is in 'rescue'.  

If your Lory has been attacked by a cat it's THE most serious of animal attacks possible for a bird and nearly always results in death as the infection from the cat's claws and saliva eventually enters the bloodstream.   If not properly treated fast, it can be a tragic, long and painful way for the bird to go.

 As for spraying anything on any bird for any reason:  No.  Never.  Other than plain water, any product that claims it will help heal or grow feathers or turn your bird into a real boy are just plain marketing garbage and if you don't remember anything else, always remember that in the pet industry there are NO 'truth in advertising' laws with any teeth.  Pets are considered nothing but property.  Replaceable like a broken chair.

 This also applies to the so-called 'antibiotics' in pet stores.  They are lethal garbage.  We have not used these on birds for decades because bacteria has evolved beyond them.  What they WILL do is kill 'good bacteria' and lower a bird's immune system when they need it the most.

 If this Lory were in my care I would be rushing to a real vet with real knowledge of avians and I do mean  RUSHING.

Just recently I've had to comfort an owner who delayed and delayed treatment of his parrot, thinking he could just 'watch and wait'.   What he ended up waiting for is the bird's infection to travel to it's heart; what he ended up watching was his bird dying in his hands.

 So please, please get this bird seen and properly treated
