We have 5 approximately 6 week old chicks. Last Monday night I noticed one was very lethargic and there was blood in the broader. I suspected it was bloody droppings and the chick was dealing with coccidiosis. I've been treating with 2 tsp per gallon of water (mixed fresh daily) with Corid since Tuesday morning. All the chicks seemed a little off on Tuesday, but now the one that was very sick and three more seem fine. However, one of the chicks cannot stop shaking. She is eating and drinking, but is wobbly and tremors. They are just some mutt chicks that were abandoned by a neighbor. Their mother was eaten by a coyote shortly before I found them when they were roughly a week old. I'm fairly certain they were not vaccinated. I have them in medicated feed, in a clean broader. Any thoughts or suggestions? Thanks!
