Had a 5 week old cream leg bar X vorwerk chuck suddenly not be able to stand up instead it now hobbles around on its elbows/hocks she's still eating and drinking and seems happy enough. I've Brough her inside under a heat lamp. I fear it may be mareks but I'm not to sure she can still hobble around walking on her elbows and balancing her self with her wings. Her poop is normal looking and her eyes are not cloudy. What do I do she has always walked and ran around fine just suddenly she stopped.
