Hi there Rhode Island Red aged 5 has been walking like penguin, she had dirty bum so I cleaned and checked her vent with finger and no evidence of egg. She has not laid for about 18 months. I had her drenched about 3 weeks ago at vet. She now is unable to hop up 15cm, wings are drooping. Her abdomen is distended. She does not seem to want to drink (there is water available) but is eating ok. She is not part of a flock so no other hens to compare, her “sister” did get egg bound several years ago and died. We are in New Zealand so pretty cold here at present @ zero at night. She is inside tonight.
