I hatched backyard mix of chicks and one of them has constant shakes. It can walk but prefers to rest on its belly. It seems like when the chick exerts effort to stand and walk is when it shakes all over. It's wings and legs tremor. If the chick is totally relaxed it will stop shaking. Reminds me of someone with Parkinsons. I wonder if it will grow out of it or should I cull? Vitamin deficiency? I did run some searches but could not find anything. Maybe there is a name for this but I don't know what it is?
