Rainbow Lorikeet attacked by Dog

Hi, my Rainbow Lorikeet was unfortunately attacked by a dog recently, and had his entire tail feathers and some wing feathers torn out and damaged. We took him immediately to the vet that day and he has been prescribed antibiotics for 5 days. Today is the fourth day since the attack, and he is still very slow, does not talk, move and frolic as normal, and is still very traumatised. Moreover, his eye colour used to be a dark amber-orange before(the colour of his eyes when he is happy), but it is now a grey-blue (representing angry/sad/low sentiments).

I know it's too soon for his psychological and physical recovery, but what do you think we should do now? Vet suggested we give him plenty of fresh water, formula and fruit every day, which we are, but is there any additional way of normalising him? Thank you so much!
