I have a 6 girl flock of RI Reds with one lady ner death's door I'm sure. I found her standing in the run, while others were bee-bopping around as usual. She had her head hunched into her shoulders, her comb in flattened down & very pale, as is her whole face. She eats & drinks like she's starving & dying of thirst. I picked her up 10 days ago & she's nothing but feathers & hollow bones, she seems cheerful tho. I put her in the isolation cage where she can still see the others. I, for the first time gave them all Wazine, (didn't know you have to worm them),I followed with a week of plain yogurt. I feed them name brand laying pellets, grit, oyster shell, & scratch & table scraps for a treat . They all live in a very nice, clean, dry chicken house with pine shavings & access to a roof covered fully fenced dirt yard. I use DE everywhere & change their water daily. After the week of yogurt, she got a little color & pep back so I returned her to the yard. At the end of the day she couldn't stand up & is now back in isolation unable to stand, she's on her side, but still happy & eating. Her poop looks like her food only mashed, a little runny. What could be wrong? I can't believe she's still alive. I feel so bad for her.
