Is it permissible to place chickens in hot water for the removal of feathers before the removal of the intestines?
Yes, it is permissible to do so. However the chickens should only be kept for that duration that enables the easy removal of the feathers. If on the other hand the chickens are kept in the hot or boiling water for some time which causes the impurities of the intestines to penetrate or mix with the meat, then the meat would become unclean, this however does not occur in the normal procedure.
