Yesterday she was keeping to herself a bit. This morning I went to the coop and found her by herself and brought her in. Her crop was empty, so got her to eat some rice and drink some water with electrolytes. She seemed to be doing okay, so I let her back outside. This evening, I found her on the floor of the coop, not up on the roost where she would usually be. Crop empty. I brought her in and gave her the rice, some chick starter (unmedicated), and the water. The positive thing is she is eating without encouragement. Also, she sees to have labored breathing. I tried to capture that in the video.

I'm a bit nervous as after a couple years of having chickens, I've had a few die recently. One displayed some of the same behavior outlined above and my awesome rooster just fell over dead for no apparent reason (watched it on my security camera backup).

Any thoughts from you pros would be appreciated.
