Oh, I'm sorry Scrambles. I went through similar with Sandy. It's very distressing. We are always commenting on how clever chooks are, I'm sure she knows you're trying to help her.
We all do the best we can with what we've got. Don't plague yourself with worry over us, we'll always support you and share advice if we can. You already have too many worries with Bok on your mind.
@rjohns39 gave you some good advice on diet and although I haven't read to the end of the thread yet, I'm sure there's lots more advice from other folks.
Also, the important thing is to share what's going on as much as possible and it doesn't really matter which thread you do it on, write about it here or anywhere else. I won't mind at all and I'm sure your other friends feel the same.
We're a small group, and you may find more advice on the sick thread, but people can be alarming, so check with us before you follow someone's advice. I trust 
@Shadrach and 
@rjohns39 and 
@BY Bob to give sensible advice that will really help Bok. Whereas other people sometimes speak like experts when they're not experts.
