We just brought her outside to stretch her legs. She was out for maybe 3 hrs in a pen with the rest of our flock. I was doing some work, turned around to check on her and found her laying on her side and she was breathing heavy. Its about 84 degrees and pretty humid, about to thunderstorm. I brought them all in and am keepin her separate. What should I do? Does anyone have any ideas of what it could be? I just got her 2 days ago from a Swap in Manquin VA. She appears to be uninjured. (no obvious injuries or bleeding...) Help Please!!!
