Nutridrench is a great vitamin and mineral supplement to have on hand, it’s a liquid that can be added to the waterer or administered directly to a very sick bird if needed. Things like pedialyte or sugar free gatorade are good electrolytes. There are powdered vitamins that can be dissolved in their water or sprinkled on food. I’ve never had a problem with them not drinking it. But you may have a bird too sick to drink on their own and would need you to help them drink it. It all depends on what situation your bird is having. There is so much helpful info on this forum, it just takes time to do the research. Id say make sure your chicks have a good quality chick feed, chick grit, clean water and brooder, safe heat source, and hopefully you won’t need these things right away. Keep an eye on them, they should be alert and active during the day, eating, drinking and pooping. If not, come back to the forum and post the symptoms and someone will help you.
