I have a day old Silkie which is doing this now. We hatched it from an egg obtained from a local organic farmer and its 11 siblings appear to be fine... It is hard to imagine it having an infection, having been isolated from the world for the last 21 days. It hatched on its own and has been eating and drinking fine for the last twelve hours, now all of a sudden it begins having "seizures": falls on its back, head lolling from side to side, legs furiosly scratching under its chin (only one leg at a time, and
i have already checked for debris/irritants), and peeping loudly... Then it is fine for a minute or two before repeating.
We have already started it on electrolytes and the infant vitamins...
Not sure if I should isolate it in case of infection... Again, hard to imagine it having an infection, and if so the other 11 have already been thoroughly exposed by now...
