PLEASE HELP!!


My little blue silkie Ethel is sick!!!
She’s about a month and a week old, and she’s been perfectly healthy up to now. Always the first to the food bowl.
Today, I noticed a weird sound coming from the brooder. A high pitched peep I’d never heard out of any of my silkies, they are generally quiet. When I changed out the food and put new, I noticed Ethel waddled over to the food with her wings hanging down, like she was too hot. So I turned out the heat lamp for a little while.
Later, I heard the sound again. I’m not sure who it was, but when I went over to the brooder Ethel was laying underneath everyone else, at first I thought she was dead.
I lifted her, she didn’t even squirm or make a fuss (she’s one of my more skittish silkies, this was an immediate warning sign for me).
Please don’t tell me I’m a terrible chicken momma, I already feel terrible about this. When I lifted her, she weighed NOTHING. It was the equivalent to lifting a pile of feathers. I lifted the other chickens, there was an obvious weight difference. I feel terrible. Whenever I put the food in there they all swarm around it, I just automatically assumed she was eating as much as the others. Like I said, she’s always been a big eater. I feel awful

School’s been piling the work on, and I haven’t got to spend as much time with them as I would like. I should be watching them more.
I have her in my lap right now in a blanket. Still not showing any interest in water, but I did get her to eat a bit.
Also, I found this in the brooder after discovering Ethel was sick (pic attached). I don’t know who it came from, but I’m super worried, and I’m keeping a lookout.
Does anyone know what I should do? Should I keep Ethel separated from the others??
