I am so sorry...this is exactly what I found last week at this time. Dawg on the forum, said it may be worms, so I went to farm store and got Wazine 17 wormer and wormer paste for horses (IVERMECTIN paste 1.87) and gave each hen a pea sized dose of the paste soaked on a cube of bread. I took one hen out of the coop at a time and fed the treat of bread, so to make sure each hen got treated.
The Wazine 17 liquid, I mixed 2 Tablespoons to a gallon of water and I eyedroppered some water in her mouth
I washed her tail area off in a warm soapy DAWN dishsoap bath at the sink and then wrapped her in a towel in a dog crate in front of a heater. She did not fight the bath. She was not breathing well and she breathed thru her open beak vs. her nostrils on her beak! ? I fed her yogurt. I have kept my sick hen crated since last weekend. I didnt think she's live thru the night but she did. The wormer has worked for now. Sick hen has solid poop again, but it is bright green and the rest of the flock has not accepted her back into the flock which is odd.
Good luck.
Keep in touch.
Praying for all of our sick hens.
