A hen we adopted a few weeks back has extreme tilting of her head which appears to be wry /crook neck. we are administering electrolytes and vitamins. my neighbor is a dog and cat vet but thought we should consider prendisone. I understand tapering and too that it wipes out immune systems for a while. I need input if you used them for a hen? ours is a large Barred Rock. if so, what amount ....for how long? and tapering? and most importantly how is the hen?
