Elsa my New Hampshire Red has been acting strange for the last 2 days. She has been shaking her head a lot and puffing up all of her feathers and tucking her head in. So I started reading a lot of forums about what could be wrong. It seemed like she had impacted crop so I gave her olive oil, water with apple cider vinegar, massaged her crop and isolated her. My other hen Rapunzel (my daughters picked these names...lol) was also pecking Elsa in the head. I checked Elsa's crop today and it feels flat and soft now. So from what I have read this should mean that everything has passed along and since her crop is not bulging and squishy she should not have sour crop. However, she is still puffing up her feathers. She is eating, drinking and moving around like normal so I am not sure what is wrong. Would someone be able to shed some light on this situation?
