Then you better listen and stop asking questions that people already told you "no". Feed your little bird at a fixed interval, you're killing it by leaving a 1 month old bird hungry everyday for 10 hours! You have to feed your bird when it needs the food, you can't make up the missing potion later by feed more often in the evening, it would probably only make matter worse, much worse.
Please please... if you can't take care of it, find someone who can to help you.
