Lethargic 9 week old chicken

[Chopper923]

After watching and reading a ton of online info, I thought I should just ask for advice. Yesterday my husband noticed one of our 9- week-old chickens seemed lethargic. We separated her from the others and made her a mix of Immune Glow we had purchased from Tractor Supply. (Immune Glow - supports hydration, immunity, and digestion per the label.) She drank some and has been drinking here and there since. She has eaten a little without our prompting, and she has access to grit. (Our chicks are on medicated chicken starter.) We have her in a quite area with a heat lamp due to WI still being cold and damp. We've only had these chickens for 8 days, and everyone else seems very active and alert. I'm embarrassed to say that I do not know if her poop is normal. I've tried comparing to online pictures, but I'm a bit overwhelmed with all of the different colors and shapes that apparently are considered healthy. One eye is shut, but there is no drainage from either eye nor from her nose or mouth. Her crop is not full/hard. Thank you in advance for advice! ❤

I thought I better repost the picture of her poop after fixing the lighting. Also, I'm including a picture of her vent.

I had to look up immune glo products, but it seems to be electrolytes and herbal oils, and very overpriced. For chickens, I prefer a good vitamin with electrolyte product, such as Poultry Cell or NutriDrench tonics given 1 ml orally for every 3 pounds. Or one of the vitamin/elctrolyte powders added to water.

At 9 weeks, coccidiosis could be a problem, in a new flock member. Signs are weakness, no appetite, standing around puffed up or hunching, and runny poops. Corid can be used in the water with no additives, 2 tsp of the liquid, or 1.5 tsp of the powder per gallon of water for 5-7 days as the only water source to treat it. Give no b vitamins while on Corid.

Thank you for replying. She passed away, and I am heart broken.
