This chicken has been fighting an illness for 3 weeks. I am at the point of wondering if she will get better or should I cull her. Hoping someone has had a similar experience or can pick up on symptoms. She is in a kennel in the warm house. Week one: did not eat, did not drink, heavy breathing, shaking head,poop runny and bright green with undigested food. Week 2: runny poop but normal color, started eating and drinking. Week 3: eating and drinking, normal poop, bright red comb, seems perfect but now suddenly can't walk/uses wing to balance. Still shaking head. I've fed her eggs, apple cider vinegar, checked for egg bound (she's not). Given wazine, poultry dusted her. So everything else is better but now can't walk, could she recover or is she suffering? Fyi- I'm afraid it is something contagious as two other birds were affected. One died (dark purple comb and heavy breathing), the other recovered after wazine/dusting. If I do cull this one, am going to bring her in for necrospy.
