I live in Virginia and two weeks ago it was 70 degrees here. For the last two nights the temp has dropped to 12 degrees. I am still new at all of this so I haven't heated my coop yet. I haven't checked the temp in there either, but all of the hens seemed okay yesterday. I have seven. This morning all of my girls popped out as perky as ever except one of my SLWs. She came out of the run into the yard and proceeded to just stand there. One of the other chickens came up and started pecking her in the face, so I have brought her into my garage studio where it is about 60 degrees. She perked up a little and ate a little scratch, some feed and finally drank some water. She is now just standing there. Her eyes droop shut occasionally. She is fluffed up. She pooped twice, one perfectly normal and the second one a cecal poop with some very runny clear looking stuff. I am getting ready to offer her a boiled egg and yogurt. I have no idea what is wrong with her. I'd appreciate any help you can offer. I have misgivings about bringing her inside, but was afraid to leave her with the others since one was already pecking at her. I am planning to install something in the coop today that will take the bitter chill off tonight, but of course only up a few degrees.
