I was dusting everybody today, and I noticed as my roo was "chewing" on my shirt that his tongue was olive green and he was breathing kinda heavily. Also, there seems to be a lot of diarrhea in the pen recently, but everybody seems healthy? Should I be worried about worms? I did find an older hen dead today, but it mostly looked like she fell off her 10 foot high perch. Which seems like a pretty good fall to me, but she would have to be really weak to fall and die. She was in a different pen (aka free range) and she had mites. Coincidence? Sorry for the combined post.
