My chicken of about 3 months or so has been acting normal and was fine when she went to bed last night, but this morning she is lethargic and wanting to sleep all the time. Normally she is spunky, talkative and loves to eat the worms I give her, but today she is just blah and her wings are starting to droop, and her stool is runny yellow but no blood. I don't know if she got into something in the yard, or if it is a parasite or what, I just know she isn't normal. I lost a chicken to the same symptoms a couple weeks ago. I hope she isn't dying.
