I have an 11 day old chick who has similar symptoms. Could someone reply as to whether they think it is. I have no experience, this is my first flock. Shes not eating or drinking very much (though she does a little of both when the others don't push her around). They're not mean to her, mind you. They do push her out of the way for food though, and she doesnt push back or jump up in protest. Sometimes she follows the others around but for the past two days she has mostly been sleeping and moving sluggishly. I would guess she is ill in one way or another, but I'm not sure how. Compared to her brothers and sisters she is very "introverted", and is constantly making a peeping noise different from everyone else's. I tried putting her in a separate container to watch her, but she cried instantly. So she's not full out crying all the time, just sounding ill at ease. I'm afraid if she doesn't pick up energy, she won't sustain herself. She is already falling behind in size, and I have only had them for 3 days.
