from what i have been reading, overstimulation can set off seizures, among other things- so if you have a bird doing that, i massage them, talk to them, drop drops of sugarwater or electrolites, in seramas its still a new breed, but they seem to have heart issues, almost like fainting goats- i am new to seramas, so am still learning- i suspect it is an inbalance in minerals and vitamins, but it still is an unknown- pm me if you need too, i am home and check periodically, i lost ruth, angel and joe to this, and thought i was losing Boaz, he took the longest to come around, talking and massaging seemed to help- so i am watching my seramas to see if there are similarities in what happened- dark comb was a symptom in all of those i lost
