last week my chicks had blood in there droppings i started them on corid the very next day and it cleared up. i stoped the corid saturday and on sunday evening they were passing blood agian so i started them on corid agian. this time its not clearing up. and one chick is a little lathargic. i went to get the goat dewormer out and found a bottel of sulmet i had no idea i had sulmet. i wish i knew that i could have started them on it that night and i probably wouldn't have lost two chicks waiting for the feed store to open. should i stop the corid and try the sulmet?
