Nothing seems to match exactly. She seems totally fine, except her legs are sticking out behind her all stiff and warm, and she isn't standing up. But if I guide her to the water she will drink, and if I put the food under her, she will eat. She also squawks and flaps her wings when I pick her...
1) What type of bird , age and weight (does the chicken seem or feel lighter or thinner than the others.)
Buff Orphington, aprox 1-2 years old
2) What is the behavior, exactly.
I got home tonight and she was just laying on the ground, with her legs out stiff behind her. She seems otherwise...
