My one little hen seems to have completely lost her sense of balance. She is about 2.5-3 months old. We kept her inside for a while and she didn't have any problems moving around inside, so I assumed the problem was that our grass was a little too long for her to move around easily. But lately, she's been moving funny even when she is not in the grass. She stumbles back and forth almost like she's drunk. Other than not being able to walk very well she seems normal. She still follows me around the yard as best she can. She still jumps up in my lap and snuggles into me when I sit down. She's still eating and drinking like normal. My biggest worry is that I have seen at least one mouse coming out of her coop, and I'm not sure if there could be some kind of disease spread that way or not. One other thing is that she is in a temporary coop, so there are no roosts yet, and her pen is actually a large dog kennel that we move around our yard every week or two. We let her out of her pen only while we are outside and can make sure she isn't getting into anything she shouldn't. She does love to play under our porch though, and I can honestly say I have no idea what might be under there because the previous residents kept the trash cans right next to the porch. So, that's our story. Is there anything specific that I should be watching for? Any ideas of what might be wrong? Do I need to worry about her spreading anything wierd to us? Any thoughts would be greatly appreciated.
