HELP – What is wrong with our chick? *Sad update*

We got 21 chicks last month, April 28th, as day-olds through our local feed store, who works with a hatchery every year to supply chicks to people throughout the later spring and summer. The chicks would be 11 days today, and all have been very healthy the past week, other than a few pastings, and at least 2 of our Gold Links have been having very runny, brown poops. Neither are pasting, but this morning one of our Gold Links has been a little droopy (and I'm not sure whether she has been one with runny poops or not). She doesn't want to eat, and would only drink when we dipped her beak into the water. She has stayed in a far corner all morning, just sitting there, eyes half-open, but not lying down to sleep. And what's weirder is that she isn't staying in the corner with the heat lamp – she's in the corner farthest away. What is wrong with her? Is she sick? Please tell us what to do! We don't want to lose her!

 

They haven't been picking on her. And she was up and active just yesterday. What is wrong with her??? I just found a tiny bit of bloody, mucous type stuff in the bedding. And I'm not sure whether it is hers or not, but it was near her and wet, but there was a sort of bloody half-firm poop that I found. They've been on medicated feed since day 1, and I've rinsed the waterers with hot water every day and refilled them with water with a vitamin & electrolyte powder added. A couple of days ago, I started giving them free grit, and a day or two later, I tried to give them some Cheerios and some dandelion. Neither impressed them. Last night, and she was fine yesterday, I gave them some scrambled egg, that was made with milk and butter, but they didn't give much interest in it, so if she's eaten anything other than the starter crumble, it hasn't been much. Oh, why is she acting sick all of a sudden???

 

What are the medication ingredients used as a coccisiostat?

 

I am almost certain our feed has Amprollium, as well as something else that starts with an 'E' although I can't remember what it was. Thanks, LynneP. She isn't doing much better, but I keep giving her a drink every once in a while.

 

...and she still won't eat. Anything.
