She only has access to water with apple cider vinegar and some nutritional yeast (for niacin). She is on Scratch and Peck starter feed. She wasn’t eating or drinking much outside (water was plain). She’s being kept indoors under a heat lamp but her brooder is large and where she can get away from some of the heat. She was shaking a bit when I brought her in yesterday and wondered if I should treat her for hypothermia (it is 80-85° under the heat lamp). She was being kept outside at about 95°-100 in the daytime and about 75 degrees at night. The remarkable thing is when she came inside yesterday and had a little bit of water with vitamins she perked right up. We then left her for a few hours not knowing what we would return home to. When we returned she had devoured almost all of her food, drank half of her water and all the greens that were in her water at that time, and is now doing fabulous! I also put nutritional yeast on her food to make sure she was getting enough because I really think it is a niacin deficiency after some research. I do not think I have been adding in enough to their feed! Just lets me know the whole flock probably needs more. She is about 90% normal right now! She still sits sometimes, as her legs don’t seem quite as strong as the rest of the flock, but she is walking much more and doing great already. I am shocked! Again, I am a newbie and would still love to hear your thoughts! Thank you so much for your previous reply.
