Okay we have one hen that we discovered tonight when we went to feed the other hens for the evening... she was in the bottom of the house, puffed up, with a dark blue/black tinge to her comb, the rest is red?? not sure what thats about. then I went to pick her up. she really didnt try to move away from me. As I picked her up I noticed she was REALLY bloated from like her "breastbone" to her butt. her skin is stretched and red, and her vent is clean and puffy a little bit. slit from side to side not puckery... if that makes sense. we moved her away and have her in a box right now away from the others... there are no signs of other illness. she walks okay doenst look to be in distress, besides just sitting all puffed up??? what could this be? thanks! UPDATE: this afternoon she is acting very sleepy, Im afraid she might die. I wrapped her up again to keep her warm, shes been inside all day, when I let her out to eat,she does walk around but is now using her wings as props to walk... I feel really bad for her. I wish there was something I could do.... she ate some oatmeal and a grape but no poop yet.... and nothings crusted on her butt... her under belly thats bloated seems to be a little blueish, sort of off color??? any advice???
