I inherited my chickens from a friend who was moving away They are hybrids and are around three years old. One of my chickens is unwell. Since last week I have seen that she has become fat, almost bloated and has a dirty rear. She is not walking properly and 'waddles' it is now difficult for her to even get out of the coop in the mornings and her comb is getting dry and lays over to one side. I have picked her up and washed her rear with warm water whilst massaging her tummy gently but to no avail. What do you think is happening, is she unlikely to make it?
