In addition to picking up the Corid to start treatment for coccidiosis, I'd pick up some game bird starter feed (at least 28% protein level). Unfortunately, chick starter feed is not a one size fits all when it comes to poults. Poults nutritional needs are different than that of chicks. In order for them to thrive they need the extra protein. Poults can crash quickly and in my opinion, not meeting their proper nutritional needs can lead to unthrifty birds which can lead to susceptibility to illnesses. Good luck with your poults. Fingers crossed that #3 made it thru the night. Hope you're feeling better as well.
