Hi, my chick of 3 months is not able to walk, she was fine a couple days ago but now she can’t want and when she wants to get somewhere she tries to walk but ends up losing her balance and falling. She also sits with one leg in front and one in back like splits. We think she might have mareks disease but her eyes are normal, she has no skin pellical under her wings and she can still move her legs. We’ve read about botulism and she has the symptoms. Before giving her anything we want to know what it is, she is eating and drinking fine, everything looks normal. We also have a bigger hen that pecks, can it be a head injury? Anything would be appreciated, what do you think it is? And how can we treat it?
