these are the egg layingest chikens i have ever seen
i have 6 Black Australorps that lay more than all my other hens combind
and thay are also Very Calm and will come right up to you and eat out of your hand. i have that will hop in your lap to be petted.
that page on slaughtering is ok , but its really not hard to leave the skin on (witch is better becase to can do what ever with the skin on like fryed and baked)
but all you have to do to take the feathers off is get you a big pot ( dont know where you can get one of thoes

and fill it whole chiken deep, then bring your water to a full rolling boil, then kill your bird (h0wever you like to do it the fastest to me is grab the chikens head and the pop your hand like you are cracking a whip, but dont hafe ass it you got act like is a big wipe and you are really gona crack it

)
post mortem hold it by the feet and keep the body under water for about 30 -45 sec afterward the feather will just wipe off it may take 2 dunks after ward you gut and cut as normal
