Please help with my sick chickens

It's easy. Mix according to the package directions into the water the chickens drink. For just a few chickens, you may want to conserve and avoid waste by adjusting the proportions downward. You may safely treat all the flock to make things simple.

Yes, but my sick chickens aren’t eating or drinking on there own so I am have to hand feed them. So I don’t know how much to give them.

Update:
Found an awesome vet who saw one of my chcickens and helped me get them all better. Gave them b12 shot, and we did end up treating them with tri sulfa. We did so for about 3 days. After that they all started acting much better eating and drinking on there own. Took them a couple of days to fully get back to normal but now you can’t even tell which chickens were sick. All healthy have there color back and gaining there weight back!
