almost 3 yrs old, late afternoon yesterday, I found my Isa Brown hen sitting on roost bar when rest of flock was out free-ranging.  She had a droopy tail, droopy comb, and labored breathing.  Several times, I offered her scrambled egg and yogurt where she was and she only took a little nibble and a little sip of water each time. She stayed in place overnight and other chicks didn't bother her.  Her body raises and falls with her breathing.  She is inside today under a heatbar.  She takes a single sip of water, then 20 minutes later a single sip of probiotic water.  She ate a nibble of scrambled egg and some feed mash.  Her poo today was all watery and green (pic attached).  She's calm and sleepy.  I have 2 other Isa Brown hens doing fine (all 3 were raised together).  Any suggestions to help her out?
