Neighbor has a hen, won't eat or drink, sounds gurgly and is coughing. Her chest cavity feels mushy and fluid filled. I brought her inside as neighbor is elderly and put her in a box, tried to give scrambled egg and water. She wouldn't eat or drink. We are trying to figure out if we can give her clavamox or maybe baytril and if so, how much. She is an adult easter egger. I washed everything completely when I came back. I'm petrified of my hens getting sick from hers.
