I have a 13 week old pullet (Sampson) and she's been "yawning" for a while. Now she's yawning a lot and is having trouble getting around. Kind of flopping. And when she's just standing there, she sometimes lifts one leg up and tucks it in. I've started her on electrolytes and antibiotics today and also started treating her with a variety of meds that I previously used on a hen that had crookneck. I'm not sure if it's crookneck or not but that's what I'm going with now. She tries to peck at food and seems to have a hard time holding it and/or getting it in her beak so she can swallow it. Does anyone have any suggestions as to what the problem may be and/or what I should do to help her out?
