I believe this one has been solved - and without a happy ending. I have a RIR pullet who can be quite the little bully. I tend to let chickens sort chicken stuff out as long as there's no major blood or over zealous floggings taking place. A couple of days ago, Thelma got to the point she stopped moving around. She would rush out if I came out with some tomatoes or watermelon for heat relief, but quickly stop and not move.
I've picked her up, inspected her from head to toe several times. I've checked her vent, looked for any mites or lice, she did have one tiny spot on a foot that looked like early bumblefoot which was soaked in epsom salt, removed, and treated. While she was pecking at some watermelon, the RIR started flogging her. The poor girl laid down and appeared dead, I swatted the RIR off of her .. and luckily for the RIR, couldn't catch her at the moment.
I brought Thelma into the house and put her in one of my big brooding boxes so she could rest. She took some electrolytes and pecked at a bit of melon, but not much. I found a couple of open wounds around her eyes that were fresh. I believe the RIR has basically kept her from eating/drinking to the point she was just too weak to fight back. When I got her, she had a bald spot on her back from over zealous Roosters. The spot healed up nicely, but she's always been a bit skiddish and very easily pushed around.
I knew she was a special case when I got her - but feel in love when I first saw her, she was so beautiful and was one of the sweetest chickens I've been around. Last night she gave up the fight...
I have put the bully RIR in solitary before to try to break her, and I firmly believe the stress and heat were what killed my poor Thelma. The RIR is back in solitary, and I'm honing the edge of my axe. I'm absolutely heart broken... I have no issue with the processing of chickens, it's part of the chicken math. I buy, raise, hatch, sell, and eat chickens and their eggs all with no issue, but when one gets bullied to death...I feel like I failed her.
