Congrats!
I actually just picked up a baby Halmahera last week!
He is about 2 months old.
I wouldn't worry about eating for the first few days. Mine didn't eat at all for the first couple days, but did drink water.
Today he finally ate! I was holding him in my hand and offered him a small plate of Wild Buffalo dog food and he took down a couple mouthfuls.
Yours will eat. just need to give em' some time
