I have a 3yr old hen that is moulting. She has always been the first offf the roost but for the last few days she paces back and forth on the roost acting like she wants to fly down but is real unsure of herself. When she does come down she walks and acts normal until she gets ready to feed. She leans over then jumps backwards 2 t0 4 steps. almost like she was dodging a snake strike . I laughed the first time she didi it but now she does it everytime she gets ready to feed. She still drinks and eats some finally. its almost like she cant focus on the ground and acts like she sees something in her face if that makes any sense.
