Or listeria. Symptoms are the same, but polio is more common in kids and listeria is more common in adults.I may be speaking out of turn here, but from what you describe it almost sounds like goat polio to me. Maybe not a full blown case but mild and degenerating. If this is the case, she needs thiamine... soon.

ETA: It is NEVER a good idea to just "worm everybody" as this is a major reason why we now have worms that have evolved and no longer die with certain drugs. You should always determine IF there is a worm problem first and if so, then narrow it down to what worms are causing the issue. Then follow recommended dosages and application requirements for the specified drugs to deal with that particular parasite. All goats are going to have worms. Some handle it better than others and it's not an issue. Others don't handle it and are always needing to be wormed, and those animals should be culled.
