hi all! I just received three new chickens from a friend who owns a chicken farm. All three are molting and look a little worse for wear but otherwise seem healthy. However one I noticed keeps puffing herself up and is shaking. I also noticed one of her eyes clouds over but then goes back to normal. I am relatively new to chickens and have never seen any of this before. I'm worried if she's sick that she may pass something on to my other chickens especially my oldest whom I've grown fond of. Does anyone know about any of these symptoms? Should I be really concerned? Thank you to anyone who might have some time to post some advice.
