Here is a list of questions to help others to figure out the problem. Good Luck.
1) What type of bird , age and weight (does the chicken seem or feel lighter or thinner than the others.). Rhodie, about 4 weeks, not sure but same size as the two other rhodies ( i have 3 rhodies, 3 barred rock, 3 golden sex link) of the same age, all birds obtained at the same time.
2) What is the behavior, exactly. doesn't move around much, wobbly when she does, hangs head down or curls it up under her chest and backs herself up into the corner, soetimes will actually be resting completely on her neck almost like she is going to roll over onto her back (somersault). She eats and drinks, and has slightly runny brownish color poop.
3) How long has the bird been exhibiting symptoms? about 2 days
4) Are other birds exhibiting the same symptoms? no
5) Is there any bleeding, injury, broken bones or other sign of trauma. no
6) What happened, if anything that you know of, that may have caused the situation. nothing (that i know of) the other birds seemed to just walk around or over her, not picking at /on her
7) What has the bird been eating and drinking, if at all. yes, some took some sugar water pretty well last night
8) How does the poop look? Normal? Bloody? Runny? etc. as stated above
9) What has been the treatment you have administered so far? quarantined to her own tub no direct heat source, and sugar water
10 ) 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? no treatment plans, do not wish to incur a vet bill on a not yet producing bird. will just replace if need be.
11) Describe the housing/bedding in use. x-large sterilite storage tub, pine shavings, indirect heat lamp (100w regular bulb) temp ranging between at 76 - 82 with ability to move to an unheated area of the brooder at will, covered with chicken wire (plenty of ventilation). currently housed in a different/smaller sterilite tub alone, no direct heat, with pine shavings and chicken wire covering.
12) If you have a picture of the wound or condition, please post it. It may help. i have posted pics above of some of what she has been doing/looking like
