Laws pertaining to Slaughtering

Using slaughtering equipment from a non-Muslim butchery

Q: I would like to know whether the meat will be halaal or not. After investigating at a specific butchery (which is not halaal as normal), they use seperate blades and machines for pork and other meat e.g. cow, sheep. What if a Muslim borrows their machine and blade (slaughtering tools) and slaughters according to Islamic way; what will be the state of that meat?

Dipping chicken in hot water to remove the feathers

Q: In many places, the chicken is slaughtered and then tipped in to the hot water and then the feathers are removed. In all the chicken shops this is the method. Is it permissible to eat this before taking impure parts? Secondly, feather removed by hand instead of using hot water and then roasted to removed small leftover feathers before taking out impure parts, is it permissible?

Slaughtering chicken

Q: I want to ask that if during chicken slaughter, the head is mistakenly detached from the body, is the chicken halaal if it was slaughtered according to shariah? Secondly after how much time can it be cooked and prepared?

Stunning of animals

Q: Almost all Halaal Certifying Bodies appear to condone the stunning of animals and even chickens prior to slaughtering. But what is the Shariah aspect in this respect? Is it simply deemed an undesirable practice but not explicitly permitted or condoned?
