I bought 7 chicks from Tractor Supply 8 weeks ago and this one Barred Rock was fine until this morning. When I let the rest of the flock out to free range she didn't come out of the coop, so I went in and picked her up off the roost and carried her out, after a few minutes she wanted to get down so I let her go with the rest of her buddies.
A few hours or so ago I went out to check on things and she was missing, not with her young flock and not with the older flock and rooster. I finally found her about an hour ago, she was trying to catch up with her "sisters", but strangely allowed me to pick her up. She was all fluffed up and seems to me to be making a raspy sound. She is content to just be held and chirp.
I have her in a cat carrier in the house now, saw her drink... she made a very small poo sort of liquid, but no blood that I could see. I have a small amount of scrambled egg in a dish for her, but she doesn't seem interested in it. She is huddled down in the clean bedding and seems content.
Something is wrong and I don't know what to do! Please, any/all advice for my sick sweet girl?
