Don't take this the wrong way, but most people that make excuses for not tube feeding end up losing their birds or they wait until it's too late to try. To quote my vet "it's not usually the disease that kills them, it's dehydration and starvation". Tube feeding requires people to locate the supplies, which does take some effort, and some money, so I'll understand if it's something that doesn't fit into your schedule or budget.
