So three of my chickens have come down with what appears to be anemia. We discovered red mites and then three pullets became very weak, two have legs that have become almost useless. And the same two have become unable to feed themselves. So all three sick ones are staying inside and the two bad ones are being syringe fed water with electrolytes, yogurt protein shakes for calcium and a quick shot of protein, and a blended mix of kale, tomato, meal worms, layer pellets, electrolytes (with B vitamins because originally we thought is might be a B vitamin deficiency), poly vi sol, and a lot of water because it was too thick for the syringe. However my Cali seems to have taken a turn for the worse, she was the first one ill and it hit her the worst but yesterday she seemed to be doing better and was pecking at some scratch I tried to entice her with and holding her head up. However today she's back to just sleeping and being unresponsive, and seems to have secreted only liquid over night. Not even diarrhea, just liquid, and she's making a gurgling sound like a stomach growl. Do chickens stomachs even growl? But she's still chirping ok, hasn't lost her voice. No visible nasal or mouth discharge. So I doubled her dose of shake today and gave her more yogurt. And gave her a drop of poly vi sol directly into her mouth. She's a 18week old EE pullet. Am I not giving her enough nutrients? Is it just a bad case of anemia? Was it never anemia? Is it toxicity? Please help. I've become really attached to this chicken.
