1) What type of bird , age and weight (does the chicken seem or feel lighter or thinner than the others.) Sussex Hen, 8 months old, weight is normal 2) What is the behavior, exactly. She is laying down, puffed up, very listless, with her eyes closed or half closed. Unsteady on her feet, lacks balance. Breathing sounds a bit labored, but not much. She went outside this morning, and I noticed she was laying down outside (unusual). WHen I got home from work I opened the coop door, and she was right next to the door and didn't get up or move. I picked her up and she didn't budge when I was reaching for her. She is not "laid out", she is sitting like she would sit in the nest box, upright with head pulled close to her body. She doesn't seem interested in walking around, and cannot get up on the roost, since she is so unsteady to even walk. 3) How long has the bird been exhibiting symptoms? One day (today - 2/7/12) 4) Are other birds exhibiting the same symptoms? Not currently 5) Is there any bleeding, injury, broken bones or other sign of trauma?
