I have a buff orpington hen, 4 1/2 years old, with a bum leg (she hatched that way, no toes on one leg). She has always done fine until about 5 days ago. I thought our single digit temperatures got to her so I brought her in. She was off balance and having trouble with her legs. It seems that she does not have adequate circulation to her legs, as they are cold to the touch. She seems to be getting worse. The leg with toes is curled and she can not get her legs underneath herself. She seems to be swollen up and as if her swollen lower abdomen is pushing her legs out to her sides. I have given her a bath and have her in the house next to the fire where she is warm. She is sleeping more than usual, but her eating habits seem normal and she has a good appetite. Her elimination is normal also. She has not laid eggs for about a year now but I wondered about her being egg bound. I'm not sure what these signs and symptoms mean. Any guidance would be appreciated. I am not afraid of vetting on my own and if I know what is going on or what I need to do am confident in my abilities. However, I've no clue what's going on here, I've not seen anything like this before. I am also not opposed to taking her in to the avian vet if I need to. Thank you for any help/advice you have to offer. Sincerely, Pamela
