1) What type of bird , age and weight. Blue Ameracauna, 10 months, maybe a little overweight 2) What is the behavior, exactly. I went into the henhouse at 2pm when I realized my daughter forgot to do her chores this morning. At the time, the hen was in anest box where she laid an egg (she started laying about a week ago). She was making an odd noise and at first I thought she had a strange eggsong. She hopped down from the box and joined the other hens around the feeder, but continued making the odd sound, like breathing through a kazzoo. She also occasionally hiccups and shakes her head or scratches at her thoat. 3) How long has the bird been exhibiting symptoms? Probably several hours 4) Is there any bleeding, injury, broken bones or other sign of trauma. No 5) What happened, if anything that you know of, that may have caused the situation. Forgot to open coop door until 2pm today. Plenty of food, but no water. 6) What has the bird been eating and drinking, if at all. Her crop is VERY full of pellet food. She drank just fine when I bought her water. The water seemed to ease her breathing a bit. She stopped hiccuping, and the "kazzoo" is not as loud. When I put the water out, she stuck most of her head into the bowl so it came up dripping - I have never seen her do that before 7) How does the poop look? Normal? Bloody? Runny? etc. Normal 8) What has been the treatment you have administered so far? Water with Oxine 9 ) What is your intent as far as treatment? For example, do you want to treat completely yourself, or do you need help in stabilizing the bird til you can get to a vet? treat completely myself 10) If you have a picture of the wound or condition, please post it. It may help. She looks perfectly normal, but opens her mouth a little as she breathes. I did not see any nasa dicharge. 11) Describe the housing/bedding in use. 10 x12 walk-in coop. She was perched on the highest roost last night as usual, with no sign of trouble. I use wood shavings on the floor and more in the nest boxes. I had just cleaned out all the nest boxes with fresh shavings. They usually have access to a covered 10' X 24' covered run, and roam free on 2 acres by day; but with the snow, the birds won't leave the coop and run. This am we forgot about the chickens so they were accidentally locked in the coop with plenty of food but no water antil 2 pm.
