Hi my hen is a Rhode Island Red and is only just over a year old. Yesterday she stood around the garden and wouldn’t move but I didn’t think much of it. She usually has a problem laying every so often because she lays double yolks and is always fine. But today was worse. She has stood in the garden and not moved, won’t eat or drink unless it is forcefully given to her. She hasn’t laid in 2/3 days and hasn’t gone to the toilet either. I’ve checked for lice and nothing, checked her pipe and nothing seems wrong. Her stomach is EXTREMELY swollen and she keeps shaking and almost falling over. She just wants to sleep has fallen asleep mid walking all day. I have bathed her to try to get rid of anything and her butt keeps pulsing. What do you think is the problem and how can I fix it?
