Hi everyone, we have a chicken who is 2 years old and has lost a lot of tail feathers recently, and in the last two weeks, has become on-and-off lethargic and low activity. She used to be very active, feisty, and always chasing food, but now she has seemed to lost interest. Her back feathers also look weird (pictures included). We possibly think she is egg bound but it seems unlikely because the behaviors she exhibits are different from what egg bound behaviors should be. She's still eating occasionally and following us around so we are not sure. Any suggestions and things to try?
