1) What type of bird , age and weight. EE, 21 months, dont know 2) What is the behavior, exactly. Let the girls out of the coop this am and nugget did not come out of the coop so I went in and she was still on the roost. She was panting with her beak open and had her wings spread. She took about 10 minutes to go from the roost to house to run. When she got into the run she just sat down and did not run around like the others. She was gone when I got home from work. 3) Is there any bleeding, injury, broken bones or other sign of trauma. No sign of trauma. Vent was clear and her crop was not enlarged. 4) What happened, if anything that you know of, that may have caused the situation. Dont really know 5) What has the bird been eating and drinking, if at all. Nugget was fine last night when I locked them up. She took treats from the yesterday also. 6) How does the poop look? Normal? Bloody? Runny? etc. Dont know. 9) If you have a picture of the wound or condition, please post it. It may help. Dont really want to post a picture. I just want to know what to do to keep the rest of my flock from getting sick!
