I believe one of my RIR hens is sick and I'm not sure what is wrong or what I can do to help. Her symptoms started recently with her laying soft or sometimes shell-less eggs, usually at night from her roost pole. This went on for a week or so and I tried adding some vitamin D and ACV to their water as well as some egg shells to their food. The past two days have been worse in my opinion. She has been staying under my deck all day and not comming out until evening when she goes into her coop. Last night she ran into the coop in the evening and went straight into a nest box and sat for awhile. I checked her after an hour or so and noticed she has some very watery poop under her. I cleaned her up and brought her inside into a seperate box with wood shavings to keep a better watch over her. She appears to have slept overnight and has continued sleeping well past the normal time all the other chickens usually get up. I've noticed the fingers on her crown have also become slightly droopy. I dont know if her tiredness and droopy crown are from her being tired or not eating/drinking or from an actual illness. Does anyone have any suggestions for what to do. The LSU school of veternary medicine is across town and does take all animals into their small animal clinic and I don't know if i should try bringing her over there or if i can just do something from home.
