Well, the fecal samples came back negative for worms/parasites. So it’s not coccidiosis! And my vet specializes in livestock so he knew what I was looking for. I’m assuming the lethargic chick just needed an extra boost of vitmains because every day it seems to do better. I’ve given fermented feed with kickin chicken brand supplement, flock recovery 911 brand water, and also tried rooster booster electrolyte water. I’ve also added colloidial silver in their water. Trying a whole bunch of more natural approaches with no medicine at all. Everyone’s combs and wattles are starting to appear more pink/red/vibrant which I heard was a good sign. Poops like normal. I just got an order in of brewers yeast, big bag of soldier fly larvae treats (giving at a minimum). Prepare, prepare, prepare is all that’s in my head lol. Thank you so much for your knowledge and willingness to help us all! See you have given lots of other tenders here great advice and mainly, peace of mind!
