Thanks for your reply! The pictures actually doesn’t show the gravity of his wound cause I couldn’t manage to remove the feather. So the whole skin piece of the top head was “detached” like I could lift it up. And the entire back neck was open, up until his shoulders. I’m not sure if he was attack by a cat and I read that if so he would need antibiotics? The problem is where I live anything with antibiotics requires a vet/doctor prescription. I only have human Penicillin V pills.The wound does not look too bad. You can put some antibiotic cream on as well. Looked like he got attacked by an older pigeon, there might be something else wrong with him. Can you take a flashlight and check inside the beak and back of the throat for any unusual yellow cheesy or whitish growths? The inside must have a nice pinkish colour.
An easier way of feeding: Mix the handraising powder with a little bit of water to form a soft clay. Then make small peasized balls and handfeed to him by placing one at a time deep inside the beak over the tongue (if the inside is clear of any growths). Easier if you have him on your lap. Feed him about 90 balls per day, divided into 3 meals of 30 each. Let him drink water after feeding. Make sure the crop empties inbetween feedings.
His droppings are very liquid and has a dark green color, if this helps with any diagnosis..
I’m going to feed him the mixture today as you suggested. Also he seems to be uncomfortable because of the louse, but with the wounds im not sure if I should wait or how can I treat the louse yet?
