Please let us know if she perks up at all, but she looks very weak. Do you plan to seek a necropsy through your state vet if she dies? If so, it would be good to call ahead today, and know what steps to take. Texas has 4 locations of labs, and is a bit more pricey, but it would be good to find out if she has anything that might affect other chickens. Take care and sorry that you are going through this.
