One of our turkeys has an injured leg. We think she may have fallen badly from a perch and twisted her knee as that is where she is limping from (though it is hard to tell). She has been like this for about a week. Her legs look almost crossed as she sometimes stands on her other foot to support herself and the injured leg sticks out at a strange angle. Her knee joint looks swollen. I know it is hard to tell, but do you think she is likely to get better? She is eating and drinking and does walk/limp around.
