Yesterday, I found one of my BEI's, at egg collection time, sitting on one of the nests, breathing rather heavily. I thought she was trying to pass an egg so I gave her time and came back. When I returned, she was still there, but I was able to shoo her away so I could collect the eggs. Later in the evening, I decided to check back, and she was outside of the nest house, with all the others and everything seemed normal. Now today the same scenario occurred. But the difference this time was, when I tried to shoo her away, she started to strike at my hand rather than get up, off the nest, and move. I'm assuming this is a "Hey! Leave me alone" behavior. But I'm worried about the heavy breathing. Any thoughts?
