One of my guinea hens approximately 8 mos old sometimes cannot move in a straight line but sways/lists to the right. She has fallen off her roosting perch at night onto her right side and struggles to get up but eventually does and is able to get back onto the perch after she recovers from the incident. Yesterday the male guinea ran towards her and she fell on her right side and spun around in circles on the ground - her left leg pushing her around, I'm assuming trying to get herself up. This scared the male away. When she finally did get up she recovered within a few minutes and joined the rest. She always is lower to the ground than the others - you can barely see her little feet - she's like a helmet gliding across the dirt. I'm thinking because of her balance problem. She eats well, drinks well, poop is normal, stays close to the older hen and is the most vocal of all of them. Unless you saw one of her episodes you wouldn't know she had a problem. About a six-weeks ago she was all fluffed up and off her feed. But she recovered within a week and acted normal until this began a couple of weeks ago. Anyone know what's wrong with her or have you experienced this before?
