6 days ago my hen (Jolene, EE, 1 yr old) escaped her enclosure and my large dog grabbed her. He was holding her but I was able to easily open his mouth to free her. I found no blood or punctures - she lost one small feather. Put her back in with the flock as she was walking around and seemed as normal as one would expect after such trauma. The next day she laid an egg but was very lethargic. The next day since she was still lethargic brought her inside in a crate to help her get rest. I fed her scramble egg. Also gave her vitamins and probiotics in her water. She was eating a little feed and drinking but still very lethargic. Took her to the vet the next day thinking that she might have internal injuries or at the least in a lot of pain. They gave her a shot of anti inflammatory (meloxicam). Vet couldn't find anything else wrong with her. I kept her inside two more nights and have now put her back with the flock. She is moving around but sits and rests. Eating but not great. Went in first last night to roost. On the poop board under where she was was runny yellow yolk looking poop. I think it was her's. She has not laid another egg since the one the day after the attack. What else can I do for her. The vet is not really a chicken vet. He has chickens himself but is not schooled in Avian science. Does she just need more time. Is it possible that she has internal injuries or EYP.
