I have a RIR hen that is about 3 years old. I saw her laying on my lawn and thought it was odd, so I went to her and she very slowly got up and limp/walked away. Then when I went to lock up my coop, she wasn't in there. I found her where she walked to and picked her up and put her in one of my horse stalls on straw. This was Sunday. So, she can't stand or walk, toes are curled and she can move, she used her wings to steady and her head to shift herself. I have had her on antibiotic (don't know if she needs it) and have been giving it to her with a syringe as she wasn't drinking or eating. I really didn't think she would make it through the night, but she did. so I have been watering her and moving her out of her mess. Today (wed) I noticed her back end was very nasty and was grossed out to see maggots back there. So, I washed her. Then let her sit in a small bucket of warm water, she just sat there and went to sleep. After I got her cleaned up I gave her some yogurt with a syringe and I put in some chick food and she ate that. She also drank on her own which was a plus, but still no standing. She is no worse, but not really better either. She is the only one with this problem, all others are healthy. She eats southern states layer pellets and gets fruit and veggies from the garden, apples, cukes, watermelon, greenbeans (not all at once, but whenever we have them and don't eat them). Her lower lids seem puffy, but no watery eyes or nose or anything. She does not seem to be egg bound, I don't feel one in there, but figured the bath and oil could help, just in case. So, I am at a loss.
