Yesterday one of the male guineas (Big Bully) pulled out a bunch of Mr. Roo's back feathers. I didn't realize how badly off he was until last night....he could barely stand. He ate but did it lying down or on his side. This morning, he look like he was dead because he didn't move. I picked him up and he 'came back to life." He took a few steps and then laid back down but more on his side. I know he's an old rooster, I'm thinking somewhere around 8 (we got him as adult). Is there anything I can do for him at this point? There are no vets around here that take care of birds. Thanks for anything you can suggest.
