Baby Woodie. Bad Injury To Beak!

[amyable]

HI,

Just brought back a baby, probably about 10 days old. It had been left in an aviary with three adults, but is certainly not able to self feed.
Only noticed when I got it home that it has a very bad injury right at the top of it's beak. Possibly been bitten as it has lost the skin at each side of the mouth. When I opened it's beak to look inside it looks like the wound has gone right through to the mouth on one side.

I've bathed it with Hypercal solution, it's very bloody and sore. Given it Aconite and Hypericum.

The trouble is he's very hungry, had been in the aviary since last night apparently, so don't know when it last fed. It's nuzzling my hand and so
I would usually feed Kaytee with syringe/ballon method, but I can't risk that as the wound is so open and would get clogged up.

Would it be able to take defrosted peas at this age as I think the only way I can feed it with this wound is by popping food in if it will swallow these. They seem so large for such a little chap. Unfortunately I haven't tube fed which might have been preferable.
I have Polyaid and could syringe this possibly if that would be better at this age.
