One of my barred rock pullets have been acting weird latley. She looks puffed up and her neck tucked in. She also keeps her eyes closed a lot and shes not as active as she usually is. Ive been keeping my eye on her and i am just really concerned. I just brought her in this morning and put her in one of those cage caddy things with some hay and food and water. i gave her some water and she drank quite a bit. I have not really seen her eat yet. I dont know what to do. She is still young and hasent laid any eggs yet. She should start sometime around this month? What are some things that i can do to figure out what is going on. She also smells fishy which is weird. Please let me know what I should do!
