Must one first perform Kaparos on himself prior to performing it on others [i.e. encircling the chicken over the heads of others]?
It is proper for one to first perform Kaparos on himself prior to doing so on behalf of others. If there is a reason that he is not able to do so, then one may initially do the Kaparos for others before doing so on himself.
 Mateh Efraim 604:6
