I was passing out peas to my ducks and chickens when my best laying White Rock (2.5 years old) raised up - puffed her feathers and went after a male duck that was coming at her aggressively. The duck is only about 8 weeks old. She was doing fine back and forth when she just dropped down and he climbed on her - I got over and broke them up. She normally does not like me to hold her, but she dropped down and let me pick her up. She is not using her left leg - just barely trying to grip with it - but no strength. Also, she is leaking a white/clear mix drip out of her vent. This is new. She is acting like she is in shock. I held her for a while. I put her in the coop (I only have three hens in there with room for 8) and moved her to a nesting box. She laid down and is breathing heavy. It is also hot out right now. Dang it. Pulled muscle? Broken leg? That fast? Why is she leaking? I don't even know how she hurt herself. They were both on concrete when they were scuffling. I should have stopped it right away, but I have to let them also sort out their social issues since they share the same yard space.
