So, I brought home 3 chickens about 6 weeks ago. They were not doing very well at the time. They were very skinny, one in particular, Brigid, who was skin and bones. I could feel the sides of her breast bone. They had some kind of protozoan, worms, mites and lice. I believe I have gotten rid of all these things and one of them just doesn't seem to be coming around. She was doing well for a while, putting on weight and starting to get more energy. Now she seems to be in a down slide. I'm having trouble getting her to eat enough and she acts cold all the time: puffed up and half asleep. She drinks plenty of water and consequently has watery poos. I've put vitamins in their water (tried putting sugar in as well), DE in their food and put a heater on them. I'm out of ideas does anyone have any suggestions? I'm desperate to get her through this!
