That's how I feed mine until they are eating on their own.Mine is older than this one now, he has all his big feathers, other than some on his chest head and under his wings where he is still bald. He's about 20 days old I would say now.
Can you take it to a vet?Now he wont eat at all, isn't begging and is sat hunched in a corner, not acting like himself at all. I've managed to get him to have another drink but he turns away any food and spits it out if i put it in his mouth. His crop feels almost empty. - this is the little one. Big one seems ok at the moment.
